Ok, if that's the case i would be super happy that would be at least something influencing the outcomes. I had the feeling something is off. It would seem that the implementation would be to blame. Yep, it never crossed my mind that anything is different. Definitely after i never have seen dialogues to change at all. Even replaying some between chapters i had got just the feeling - you can go for more sex scenes or not to view them, maybe influence the rest of the girls by hitting on them... More likely the Anxiety bars or Prudence - those fluctuate for sure. Wondering now if it would be only the bars + some choices (girls) in the game. But for the favor i will start to name it Game Novel from now on. I would say it would be fair for now(?).
So the factors should be:
1. Anxiety / Prudence
2. Hitting on other Girls or not
3. Going brothel/Church prostitution
4. First choice: someone significant / girlfriend
Do i miss on something else? Because stats with sex and Perks seem not to change between chapters (they change exactly the same in same situations). And the MC have got no influence on this one. As long as only Golden Boy is taking care of both of them.
Okay, because you obviously came into this game/thread quite late, I can at least give you the rundown of what we KNOW for a fact about the game's final bits:
-Game was confirmed to have multiple endings since the beginning. There is at the very least 3 endings, originally Fujino only confirmed two ("Kirito doesn't know", aka the typical unaware NTR he's a big fan of, and "Kirito becomes a willing cuck", aka he finds out but gets off Asuna being fucked by Inoda), but this was before the game properly started and the plot massively changed since then, the introduction of stuff changing depending on how you treat the other girls and Kirito actually getting 'lucky' with them basically confirmed there is at least one more ending, maybe more but we don't really know any exact details of it for now.
-Your choices regarding the other girls matter, albeit to a very small degree until late game. Essentially, Fujino started adding the option to specifically 'personalize' how you've been treating each girl in the game from Kirito's PoV after a certain point, originally there wasn't such a thing, and while very small changes so far we started getting stuff that was different depending on if you had made Kirito more willing to 'cheat' with a girl or another specifically and in general, beyond just the 'prurience' (Perversion) bar. For example, only if you have made Kirito give in to ALL the other girls' advances do you get the short dream/CG scene of him fantasizing of all other 4 girls in bed with him, while for Liz individually if you had been giving in to her advances or not her reaction after the scene where Inoda turns her into a succubus, fucks her and then brings her to 'see' Kirito (Who thinks she's just a familiar NPC who looks like Liz) changes, as it changes a bit what Kirito said about her. Another example would be how if you reject Sinon when she wanted Kirito to help her in that publicity stunt they recorded at his workplace, she will be fucking the dude she blackmailed to get that gig going, while if you don't, she will just be femdom-ing him without letting him actually touch her.
-Fujino announced a bit ago, and with the latest report confirmed, there will be 'Epilogue' content after he finishes the main game. We're still unsure of what this means, if it means he will add more ending or if it means he will add more scenes after a certain ending, all we can do is speculate on that now.
