Halo 2 is way older. I enjoyed Gears of War because it was the first next-gen game I really got into. I'll compare the two when Halo 3 comes out. Right now though, speaking after I've patched, I'm thinking Halo 2 might even beat it. Seriously, you get paired with a random team. It's a tactical game, and no one can use any tactics because they don't know who they're playing with. That really irks me.
