more like new events. I will write it here at some point
Ok here is my main thoughts about it:
Purity/Corruption/Blackmail System in UD is mostly done right and it's 100% playable. But it lacks focus and consistency. An example, Most corruption routes (Sister, Sarah, Lisa, and Kimberly) corruption are just blackmail, you got dirty on them and now they are forced to do as you wish. so it doesn't make any sense that it's something else.
What I think it should be:
Purity: Peter does not do or say anything morally wrong, he uses his "innocence" to get the girls to do as he says and perhaps even fall in love with him. So most of the scenes are just the girls doing it because they want and it's the most "natural" route. The manipulation power is only used for the first and final push. Peter is this version is most of the time a "normal" kid who just wants to help people in need and gets rewarded.
Corruption: Peter keeps teasing the girls until they gave in to their temptations and keep convincing them to make more and more sexual stuff until they are completed addicted to him. Peter in this version is always in control and expects more of the girls.
Ex.: Sarah, Lisa, and Kimberly are not blackmailed in this version. Peter keeps teasing them at the park until they gave in. there is no blackmail, that's left (obviously) to the blackmail route.
Blackmail: Peter gets dirty on the girls and now they are forced to do as he wishes. There is not a lot of mind manipulation. It's just straight peter forcing them to do as he wants. Perhaps if it's mostly people's interests, Peter can mind-break them at the end of this route.
This is not really that far from what we actually have in the game, so little re-writing would be necessary. But I think the possibility of choice would make the 100% more replayable
*Not all of the girls are going to get the three possible outcomes since it wouldn't make sense or just be redundant. Dizzy as an example just loves the shota dick, so what's the point of a Corruption/Blackmail Route.
Events Ideas:
*Sidney waking you up - Mom always wakes you up and gives you possible scenes. But what if there was an option where you could change who wakes you up like Sidney? It would be the same thing but with her instead. I even had the idea of creating a new character based on it. An maid or cleaner at the house that would also do it.
*Parents teachers meeting - This event would just be an excuse for certain characters to meet each other and Peter fuck them at the same time. You would talk with the principal or Jennings and the event would happen and you could get certain characters to meet you somewhere in the school.
*Sleepover - In the game at some point you can enter any character's house (if they have one), but what if to Kimberly and Msr. Amos, you could spend the night at their houses and fuck them while the girls are asleep. (This is one that would not be a priority since to make it unique it would need new scenes.
*More meeting in the overworld - We never get to fuck Sarah and Lisa outside the park (together I mean). Maybe they are both buying groceries and you get them there, or even in the middle of the street. The same thing with Dizzy and Sidney, they never hang out, so something like that would be nice.
New characters Ideas:
Maid - Peter finds a Maid/Cleaner in need of a job, you ask Mom if she was willing to hire her. If Mom has a certain amount of points, she says yes.
Mom's Boss - We never get to see where she works or what she does, So maybe having a building where so goes during the midday. You go to meet her (and obviously have sex) but meet her boss instead.
*Purity - She caught both of you having sex and threats to tell the police. Peter offers to help her at anything so she keeps quiet.
*Corruption - None
*Blackmail - Peter needs to find something to make her quiet and control her.
Nun - Glassfish has an OC that's a nun, so yeah...
That's what came to my head if you ever find interest in any of what I said. I'm more than happy to make more scenes or even write them. The only thing that I can't do is use the RPGMaker.
