"Finally, pregancy mechanics for that one guy that keeps asking about it"
I'm not that one guy, as far as I know, but I'd be all about about some pregnancy options being added. That said, logistically I know Oni isn't up to that kind of task and I'd rather Oni refine the art style of some of the girls to make it more uniformly consistent than adding pregnancy options. So make of that what you will.
What I would like to see would is a new mechanic and character like Mystique being added to the game to spice things up a bit. From a story perspective you'd catch her snooping around the mansion and instead of turning her in to Xavier you enlist her to help you persuade the X-Women into being the kind of girl you want them to be, for a price of course. She wouldn't be in the mansion so you'd need to call her to hang out or to send her off to work for you making her the hardest character to get while being the one that helps you get other girls easier.
Basically, the mechanic would be you call Mystique up and pay her to help you with a girl, letting you boost or lower a targeted stat without dealing with the grind or having to chase a specific girl down. This would help you better tailor girls responses and work as a simple built-in 'cheat' system giving the user even more control over how they enjoy the game, while letting you tailor your girls behaviors to better please you. The twist being that is Mystique's stats and preferences are also affected in the same way as what you tell her to do.
For example: If you pay Mystique to make Rogue more obedient for you, Mystique's obedience level will also increase. If you want Mystique to make Laura prefer anal sex, Mystique's preferences will change accordingly. If you want Jean to not be an exhibitionist ask Mystique to fix that too. The effect would be proportional to the price so a 50$ love increase/decrease will modify a selected character and Mystique's love stat by 50 points. Trait modification (exhibitionism, sexual preferences, etc.) would be 100$ making it the expensive fix for that one time you accidentally asked a girl for something you didn't want, or she started doing something you didn't like.
I know my idea is probably too challenging for Oni to implement but I figured with how stale the grind can be with this game giving us a tool like this outside of using the console commands would be a nice change of pace as well as add a bit more story and immersion.
Just my opinion, but feel free tell me what you think. Do you like the idea? hate it? Want Oni to implement it?
