I like the idea of the questions. You get some questions when you make a new character on GW2 that do have a bearing on what story your character plays out in the beginning.
I would hate to be locked into a particular character type though. If you used the questions like GW2 only to set a character’s background and storyline, that’s one thing, but I have played games where you can get locked into a particular class or race that maybe isn’t what you’re wanting to play. I try EVERYTHING. I love to play alts. And in one game (I can’t remember which now – been too long or i’m getting too old) I always got locked into playing healer until I finally figured out a way to let it skip the questions and let me choose for myself. So I would say, don’t make it so locked in that someone can’t play a different way. 🙂
