Halo games are awesome. I do not have an X-Box, or the games, but my cousin does and I love those games. They're awesome, and so is the gameplay. I don't know about you people, but I liked the plot and storyline. I thought it was good. As for half-life and that other crap, never played those, but they all seem kind of like take-offs. Halo 1 and 2 are great games, especially since you got to be an alien dude in the second.
