Haha, WolfCatBot. I'm going to eat you alive, you pathetic little s**t.
It would have to be an RPG, of course.
As for the setting, an Old West (realistic, GURPS maybe) RPG would be nice. Cyberpunk (Shadowrun maybe?) would also be pretty cool. Or maybe some straightforward horror game? All in all, I'm leaning towards something PNP-inspired.
