Halo 1 is a very good game. I liked the plot; I read the book. IMO Halo 2 sucked. I was expecting the whole thing to be on Earth, but it wasn't. Halo 1 on Legendary on the PC is easier since I find it easier to aim with the mouse rather than a silly thumbstick. Halo 2 seemed somewhat of a mindless killer. Halo 1 & 2 are very unique in my book in the fact that they're cooperative and I really love that. Now if only they had Halo 1 co-op for the PC version, that would be extremely fun!
