Quite frankly, left 4 dead doesn't appeal to me. I was watching some reviews last night and basically it's just running around shooting zombies with no story what so ever behind it. While the co-op does look fun, I think that I would get bored of doing the same thing over and over again. Also I think there are only 4 guns(not sure, but I think that was the number) so there isn't a lot of variety, and on top of that, the graphics didn't look that great, however that might have been the video I saw. On a lighter note, the pipe bombs look fun.
