I am not familiar with the Online Play / File Count /File Size thing. At some point your game will outgrow it. There are many scenes that need visuals. Many events can and should be extended. (Café shop the guy that want to show MC-F something - and gets a hand job maybe extended to BJ and then to Sex (A and V) for more money). And i haven't'd started with all the other chars in the rest of the game.
For restrooms: At any restaurant, café or Ice parlor (change cloth) there should be two one for customer and staff (in there room). At Alex corp on each floor. (bathroom penthouse - fun in the tub!?) First to reflect a little bit of reality and for funny things to happen with different NPCs.
Here is Example that messes with the stats and "in game reality".
Erin: Fun with MC-M - no fun with MC-F unless Arousal "critical" than MC-F despite having a Dick gets eaten out. If MC has chameleon and Body is male "he" can have fun with Erin again.
- Male Body = Dick
- Female Body - Dick or Vagina
What do you think is missing there? (Sorry I didn't have the time to be more specific due to RL things)
Until next time, :)
