I guess I tend to be either the most sneaky, sinister class or the biggest, most straightforward powerful class. In WoW, when I had an account, I had an Orc warrior and a Blood Elf Warlock. In TF2, I usually play Sniper or Spy, but sometimes I play the Heavy. In Fallout 3, I specialized in speech, guns and explosives. In Fable 1 I specialized in agility/dodge moves, but in 2 and 3 I focused on firearms.
Interesting trend here. Wonder what my psych professor would say about that...
