I have to disagree at all on the Halo1 part (I played it on the pc), the singler player was VERY shitty, the rooms in spaceships and buildings were all the same!! And then, afte enduring such pain I get to know space zombies (they're probably not zombies as I didn't played after that to know)!! I usually like this kind of sci-fi stuff, it was reason I started playing it, but this is just too much. The online part was pretty nice though.
