You guys are sooo cool, I mean I wish I could be that jaded.
Halo is a good game. It's not as fantastic as it was hyped to be, but things that become "mainstream" successes like Halo are always exaggerated.
The performance is really inexcusably shitty. Turning off the framerate lock and turning off specular pretty much fixed things for me, but it still isn't perfect.
cia, I don't know what game you're playing, but the AI is quite good, one of the high points of the game. If you don't like the level design, that makes sense, it can get really repetitive and boring really fast, but the AI and the enemies are one of the coolest parts of the game.
And to the guy who said that someone must have been referring to the beta version, the final game has been available online for a few days now.
