Just read up on Rare's random character creator for SoT. Rather naff for a game of this type. Not having the ability to put a pirate version yourself into the game, just some random Rare created bod? Shame.
If at all possible I try to be a robot or cyborg, I always used to be a robot on phantasy star online, I then try to make the robot what I consider bad ass, if I need to be a human then I make it like me as much as possible.
The real exception is wrestling games were I always try to make my character look like smash or axe of demolition...... Huge huge Demolition fan.
