If you like violence, the new Doom series really gives me a pure rush. The game is a lot more exiting these days than the earlier ones because the game rewards you if you play aggressively and don't stop attacking the enemy. So in that game world you exist between a much slimmer "happy medium" between life and death, you're always right on the edge. I've needed to calm down with a book or something after i've played that, can get kinda intense lol.
