I think I can see how Halo appeased a lot of gamers since it had the good stuff like blood,and gore but Half-life had more than just those Half-life required you to think, but i think its the person's choice to which he/she prefer better. I like Half-life though
I admit, Halo has a rather impressive arsenal and a pretty cool suit, but the HEV suit is cooler, and while Halo's story is weak so you can get straight to the shooting, Half-Life has a logical, interesting storyline that could be a book (except the G-Man, that is a little corny)-and you still get straight to the shoot 'em up. And, Half-Life runs on Source-a much more reliable engine with much better physics. This engine allows many other possibilities and almost all Valve games run on it or a variation. Plus, while it is much better on PC, Half-Life 2--Half-Life 2 episode 2 and other source games are also available for Ps3 and XBox 360, while Halo 3 and future Halo games are available only for XBox 360. This is why I do not play Halo 3.
you shouldt try and compare, bungie made the last 2 games to be kinda like the first only getting better, bungie also made the Marathon series, i hate half life simply for one reason.....................................................................................................MY MOTHER IS A FAT WHO** look just dont do a vs with these games, gordan is a scientist, and master chief is a superhuman
