i still wish the girls were more diferent in therms of gameplay. i said this a few times already but, rogue being "clingy" because of the addiction is the only thing that set her apart from the others. to me, each one should have something that they want from you.
kitty could have some "dad issues", while Emma would be more exibitionist(since she is used to being in control), Jean would be great to have some sort of sub/dom mechanic with the phoenix, help her become more submissive, and she will be able to control it better, let her become more dominant, and the phoenix will get in charge.
also, why not give us a job to make some money? it would be a great way to pass the time and make sense, hell, set up some diferent jobs, i could see for example, a research group with beast, to find why your powers work like this, or a help group for students like rogue who have dangerous powers, maybe even a "police" esque internal security team, that deals with brawls and fights between students.
so many possibilities, with not really that much requirement, and it would make the game much bigger very quickly.
to be honest, this would actually make the game better than the half assed thresome mechanic the game has.
