I'd be in Mass Effect, yeah! I'd probably just go around on a day to day basis, it seems like it'd be a society that'd be fun enough to just live in.
I'd probably also stand around, anxious to give a quest to Commander Shepard. Or if I was really lucky and blessed with some sort of combat ability, I'd ask to join Shepard's party as a sentinel.
After a few conversations I'd then open up to Shepard, spill my ultimately traqic life story, have Shepard help me to set things right, and then if Shepard was female I'd be ready to be a potential romance option and have the chance to experience what is undoubtedly the best sex in the entire galaxy. (Judging by how many people want to bang Shepard.)
