for ride or die, i was really hoping for someone that he grew up with. trevor had a working class family and he was a trouble maker back in the day. sometimes still so.
high school gf - he dated her basically sophomore, junior, and senior years of high school they were always together. probably had most of their firsts together. they're still pretty good friends now.
the casual thing has the most freedom as for character creation. i don't have any details really. i was hoping it was current and somewhat recent.
