It's not as great as people are making it out to be. It's basically the first game with slight control differences, and better levels. That's really about it.
Have you played it? It's exactly the same as halo 1 just with (as i said) control differences and better levels. (i'm not including stuff such as new enemies, new vehicles, and new weapons when i say it's exactly the same as H1). And joust is right, HL2 all the way.
