I wish the race made a difference to your stats. Since I stare at a character's cloak and helmet most of the time, I don't even remember what race or sex they are.
Either armour/speed/recovery or the strengh/discipline/intelligence
A small stat boost won't pigeonhole races into classes, since a lot of people might want a more agile Titan, or one with better special recharge.
I'll go either human or robots, whoever get's the best dance animation. The awoken look like they've had a makeover from their emo teen sister.
I'm not sure why I get to be a male or female robot, but I guess it made sense in Futurama.
