uhm..., well it would kind of depend XD
I dont mind if you play as a villain, but since I have a lot of missions I need to work your villain in as well, changing things A LOT, to start with, I guess you want your villain as your main char and thus most active, but that would require me to change the missions to include yours, what might be pretty tough job
plus I want to have someone on group that is not controlled by me for the home like situations
