I forced myself to quit last night. I don't want to burn through the game in two days. Of course the deathmatch will be appealing for a long time.
Really enjoying the high-quality cutscenes and story line. Also getting to play as an alien soldier is a nice change-up.
Damn, Halo 2 this week and Half-life 2 next. All I need is some Depends and I'm set for a month.
