I always get a rush playing MW2 deathmatch games. Say what you like about MW2 (and many do), but in a game where you can only survive 2 or 3 rounds, trying to link together a 9-kill killstreak for a Pavelow is a huge buzz. If you get it, of course. It's a huge buzzkill if you get tagged a few kills short. 9/10 rages in MW2 occur because the deceased was knocked off a killstreak run, but hey, that sense of risk just adds to the high.
