Preferably FPSes. Which game(s) give you that insane adrenaline rush? Out of all the games I've played, I'd say Quake III Arena is right on the top of the list, especially on those maps where you bounce around with no floor below you, and the instant respawn times. Or maybe Unreal Tournament, but I don't think it even approaches the speed Quake III.
Serious Sam could be another contender, with massive amounts of enemies on the screen at once and usually massive-er amounts of ammunition to blast away.
