The length of Doom 3 is the reason I won't play it twice. That, and the fact that the game is a little offensive morally. I played "Halo Combat Evolved" three times. It was fun, had a cool soundtrack, and wasn't too long. I found it hilarious the way the dumb aliens died. Of course "The Flood" swarms were a little disturbing. But that was nothing compared to the monsters and the special effects that terrorize from start-to-finish in "Doom 3". If I can't get my hands on Halo 2 next visit to the video store, I'm thinking I might get "Chronicles of Riddick", or maybe "Unreal" or "Quake", or maybe "Oddworld", that one looks like it might be fun.
