Ugh... guess its time to finally do this. The final mechanics dump that ive ran across. Its not going to be *everything*, because its impossible to measure everything with the tools we are provided, but i will only post stuff i could measure, based on observation.
But before i get to that... a funny screenshot taken in a VERY (5 weeks in) long session ive played some time ago about how inept the AI actually is without external help:
Now the guy can do all the sexual stuff by grinding the handbrake, without the help of all those horny women, who absolutely hate his guts... or turn homo - he will have more luck that way. My portait is empty.. anybody noticed that? Haha.
Anyways... where to start?
1. Traits.
Traits are generally considered irrelevant in the grand scheme of things, but in reality traits heavily influence the behavior of a card. Sometimes to a degree that makes it impossible to get in their pants, especially when combined with things like lowest/low sociability. I will only mention a few mechanics related to those the (lying) wiki didnt mention. As a rule of thumb - ALL traits should be considered bad. With the exception of a few that arent, that is, which i will mention here:
-"Bad with x trait". While it makes getting in the pants of the individual in question more difficult, its actually a beneficial trait, as it makes the card immune to MM (we know what that is, right?).
-"Easygoing", "Obedient" and "Perverted" traits. Cards with these traits will gain love count quicker. Sounds great, right? You can quickly gain love count with such a character (as quick as 1 or 2 break periods to reach relationship level), without having to go for the long grind... except... the same rule applies to other cards. You dont exist in a vacuum, after all, and other cards interacting with this character will also gain their love quicker. You see the problem here, right? "Easygoing" trait also makes the card having it more eager to seek out new relationships (similar to "Trendy"). Beware.
-"Affable". Makes the card gain increased like count. Particularly nasty on orientations leaning in the *other* direction. Receiving praises from such a card is devastating to your LLDH.
-"Charming" and "Chivalrous". They effectively do the same thing, except the first for hetero, while the other for the same sex. Cards with these traits seem to be particularly susceptible to MM. Sometimes to a point, where competing over them RAISES their love count of the loser, rather than diminishing it. Oh, and... cards with these traits do not get more traffic in terms of interaction. Not in a noticeable way, at least. Another slap on the wiki...
-"Tsundere". I dont know if the card in question is less likely to join group activities (as the wiki claims), but what is certain is that with every love count gain comes a hate count gain to balance it. How does that work? Its hard to say, but this trait makes it impossible to get into the pants of a lean homo chick, as her love count gain will be equalized by hate count. The orientations more in line with the character attempting to get in their pants fare much better. The hate gain ceases once you cross the 21 love count threshold (or, at the very least, isnt as noticeable).
-"Serious". On top of what the wiki states, this trait will make the card have lowered sex talk % chances. Significantly.
-"Impulsive" makes the card with this trait either extremely easy or extremely difficult to interact with, depending on the state you find them in. Its... its awful, alright?
-"Jealous". Now... i dont have enough info on this, but i did run into an interesting situation, where my partner, who happened to have this trait, accused me of cheating... repeatedly. For the record, i did not cheat on them - i even went to the statue to check if she had the "Cheater!" status against me. She didnt, but that didnt stop her from issuing "warnings". My guess is, that theres a whole other plain of "cheating" that cards without this trait do not perceive. I would just call it "flirting". We know what constitutes cheating, yeah? Well, i think "flirting" can be anything from love/sex talk to massages and headpats. Its hard to say. Avoid cards with this trait - its frustrating dealing with someone acting this way, not to mention the damage to LLDH they cause with each warning (5 hate and 5 dislike count gain per).
-"Asexual". Just like "Serious", on top of what the wiki claims, it also reduces % chance of sex talk. If you combine the two? Oof. If the character isnt in line with your orientation and you cant use love talk to reach the relationship threshold, forget trying to get in their pants.
So, are there any good traits? Sure... four. Three are completely cosmetic, that being "Sweaty", "Diligent" and "Always hungry", while the last, "Scheming", increases the efficiency (not % chance to succeed!) of bad rumors, allowing you to completely destroy someones opinion of a card in a span of one or two break periods. With three successful bad rumors the card gains between 7-8 dislike count towards the target. You do the math.
2. Interactions.
There was a time, when ive complained about love count sources apart from sex talk and contact tab. After digging some more, i found more that do just that. But first...
-Praise. Useless interaction on first glance, but it actually has a function. While Encourage and Calm exist, Praise does the same thing, effectively. Succeeding with it nets you 20 partial love and like points. Failing will gain 10 partial dislike and hate points. Why use it? If the target is incredibly pissed or incredibly sad, praising them will normalize their mood, regardless of whether you succeed or fail. Kind of an oversight by the devs.
-Love talk. This one is interesting in how it works - lets assume that you are a hetero character trying to get in the pants of characters with the following orientation (ive used the training bonus cheat to figure it out, to get a clear read on it):
*Pure hetero - after three love talks, gains 3 love count
*Lean hetero - after three love talks, gains 3 love count and 1 like count
*Bi - after three love talks, gains 3 love count and 3 like count (the worst option, eventually leading to equalization of points)
*Lean homo - after three love talks, gains 1 love count and 3 like count
*Pure homo - after three love talks, gains 3 like count
Invert for homo characters interacting with who they favor. Obviously, traits can swing these gains wildly, but this is for characters with NO traits altering LLDH gain, whatsoever.
-Massage and inviting to lunch/to have a rest - both gain love count. Not much, but every little bit helps.
-Headpats ("Caress") also increases love count. Its too difficult to talk numbers here, but it looks like its a split between partial love and like count gain. If we consider the partial point gain to be 100%, giving someone headpats will result in 90% love gain and 10% like gain. Worth using.
-inviting someone to the restaurant and going home are also a split of partial points, with partial love points having a larger % than like points - not entirely useless. Karaoke and arcade invites are mostly focused on like points - avoid at all costs.
To close this one up, interactions are either a one dice roll (or a 0/1 situation) or two dice roll affairs. Every interaction that has a note afterwards ("Had a deep conversation/Conversation didnt go anywhere", or with massages, "Cop a feel/You were told to stop") can alter the point gain. Even if you succeed on the first roll, you may fail the second roll. Im not a fan of this, personally - i like Rogue-Likes, but this game shouldnt try to act like one... thats just me, though.
3. AI interactions/differences between PC and AI interactions.
-First off... rumors! While the PC spreading bad rumors generates dislike points, a single bad rumor by the AI makes the target generate 3 (!) hate points towards the card mentioned. Good rumors seem to be the same on both ends (as in, increase like count only).
-AI constantly asking whether youve had sex. I... honestly, this interaction is just a time waster. I havent seen a change in LLDH resulting from either answer, so tell them whatever if they ask. It might be prudent to answer "no", if its your lover asking. If anything, you wont ruin their mood.
-AI asking whether you like/love someone. If they mention themselves - i leave the answer up to you. If its your lover asking, and they do not refer to themselves, the answer is always "no", lest you risk incurring their wrath, and the "Cheater!" status in the process.
-AI asking whether youve had sex with someone. Obviously, if its your lover asking, the answer is "no", but if some other NPC is asking, replying with a "yes" generates bad LLDH (might be hate?), while a "no" gives them love count (where applicable). The exact numbers are impossible to state - sorry.
-while the AIs LLDH makes them behave in one way or another, the PCs LLDH is irrelevant. Your character might hate the guts of some card, but as long as their LLDH is positive towards you, they will interact with you. Ive played as a pure homo character to test this, and chicks wouldnt leave me alone, in spite of me having no love count towards them...
-the AI ignores the "Unforgivable" status, when interacting with the player. The player may have this status, which bothers the AI, exactly, none. You wont even hear an apology for... whatever it was they did.
-there are two AI exclusive interactions that i have no idea what they do, in terms of LLDH change. One is some card bragging about having sex with someone (i can only assume its an attempt at sabotaging their LLDH), while the other is making fun of "Lovers quarrel", which involves the card mentioning it witness someone having sex with not-their-partner, and being competed over by their partner.
-youre not being clever by dragging your side-chicks to private rooms - the AI knows youre cheating on them, even if they dont generate the "Cheater!" status towards you. They will always mention something alluding to you cheating on them ("Unfaithful...", "Why is everybody constantly sneaking around? I dont mean you, specifically...", "Keep your excesses down, will you? Its too easy to tell what youre doing!"), after youve had sex with someone other than them (this also applies to having sex in the open, and getting away with it).
-the infirmary is the quietest spot in school... the AI is incapable of finding you there, if they hadnt already began the action involving you once youre there, meaning, that you can drag your side-chicks, or when cucking someone, there.
4. Random info dump.
-"Cheater!" status persists for 3 days since it was earned. In those 3 days you might get bombarded with warnings about cheating, destroying your LLDH in the process, or... nothing will happen. It can go either way, but im guessing that your lover needs to have someone lined up before they start issue warnings.
-in spite of following the anti-cucking guide of mine, you may still get cucked. Its not that my guide is wrong, of course (heh heh)! Its that if your lover has over 21 love count towards the other guy, they might compete over them, if they spot them fucking someone else in the open. There is a small chance that the guy has less love count towards the individual theyre fucking, than your lover, which will make your lover win the competition (how did you let your lover have this much love count towards the other guy in the first place...?).
-the "Force" interaction.
Early into playing this game, i found this interaction pointless. Now i find it crucial to my play style. Forcing your lover to have sex prevents them interrupting the sex session, if seen. Simply put, it takes all control away from them, and transfers it to you. The uses are plentiful, but one worth mentioning is this - there are exactly 7 private rooms you can drag your lover to, but normally, you can only use 3 of them (the room in the gym, counseling room and the hotel; im not mentioning your room/house). A character, once forced, becomes completely subservient to your whims, meaning you can drag them to the changing rooms or the toilets. This is in stark contrast to what is "normally" possible, as outside of lowest virtue cards, nobody will follow you to gender restricted areas.
-making "useless" sex friends?
Sex friends youve made via competitions will either fuck you, as long as your LLDH is high enough, or they wont - depending on their virtue. Force interaction will allow you to make use of those higher virtue cards, that have over 21 love count towards you, but will not normally fuck you due to their virtue. Use it wisely... but dont let that love count drop below 21 and THEN try to force them - they will instantly hate you for it, and you (as do i) probably want to avoid fighting chicks, right?
-relationships and "waiting for sex" times.
Normal virtue cards require 1 day to pass, before they put out. High virtue cards require 3 days to pass before they allow sex. Highest require 6 days to pass before they allow sex (no sunday date needed). Ive already mentioned that at one point, but if you became sex friends with them beforehand, the wait is gone - the second you get into a relationship with them, they will fuck you instantly.
-people running our of the room upon witnessing someone having sex: each time a card runs away screaming, they just gained 15 partial hate points towards the fucking couple. This can stack up really fast, if the couple is fucking in one of the main traffic arteries of the school. For other contact tab interactions, its 15 partial dislike points, instead.
-interrupting when some cards are fighting or fucking - avoid doing either. Interrupting sex is particularly nasty to your hate count gain, if you dont intend to compete over one of the parties.
-competing.
This should be common knowledge by now, but if you intend to compete over someone, you need to click on the character you want to compete WITH, not OVER. In other words, if your lover is talking to some guy you want to shoo away, you click on the GUY, not your LOVER, and then hit "Argue". Otherwise you will just make a fool of yourself, competing with your lover over the guy...
Then, if you really want to interrupt a fight, click on the person you dont like or care about, rather than the one you do, since its them that will get the most dislike/hate for interrupting.
-the teacher.
The teacher, in the grand scheme of things, is just a cock block. However, you can make their existence less of a pain, if you select a card for the job with low/lowest sociability. They will most likely run away upon witnessing sex, rather than interrupt it. The teacher also emits an aura (you can easily tell by the music changing) that dampens sex talk % chance and contact % chances, so be aware of where you want to woo the cards, as the teacher will most likely foil your attempts. Teachers with low and lowest virtue will fuck anywhere, but normal, high and highest virtue teachers will only fuck in one of the private rooms, unless forced by someone.
-class prez.
I have seen the class prez bust the teacher for fucking with students, but ive also seen the teacher get kicked out by regular students with highest virtue. If you play as the teacher, be aware that its is a thing.
-students (and the teacher, i suppose) gaining supernatural speed from time to time, whilst not having the rainbow card trait.
Ive mentioned this fairly recently (on the last page?), but this is directly tied to a certain stalking behavior of NPCs, once their love count exceeds 21 points. As mentioned in my last post, when an NPC has nothing to do currently, they might zip over and stick to another card they have a high love count with. Ive seen it happen with cards having high like count too, but it doesnt appear that often with those as with high love count ones.
Phew! That was a long one. Fortunately, this will be my last post on the topic of mechanics. Not much more is there to say about the game, i think. Pardon the chaos of this whole thing - its been written "on the knee" for some 2 hours straight, as ive tried to recall the "things i have seen" (and i still may have missed some... oh well).
