In Fallout, I'm a super nice guy but its because I play the games pretending I'm the Venture Bros. so I make the nice choices and the absolutely stupid ones. Talking to prostitutes is funny and not using guns in a fight with Super Mutants when you are built for science and running away is amusing.

In MegaTen, I tend to be apathetic unless being good or a jerkwad nets me something (damn Social Links) though I mix it up to keep me from being Neutral alignment since I take the Palladium Books argument that Neutral is technically impossible and selfish alignment is more accurate to what neutrality is.
