Modern Warfare 2 is very popular, but Halo Reach is still in production (yet looks very promising). Besides, which is better is more of an opinion anyway.
As stated above it is an opinion. Depending on what gameplay you like, art style, map themes, and more you could love one and hate the other. I agree with the previous poster, Halo: Reach looks very promising featuring Spartan IIs, not the Master Chief. You run with an entire squad instead of on your own, and there are female spartans. As well as major graphics and SFX overhaul, the game looks to be superb at this point.
I would say halo reach because of its multiplayer experience is much better than 3 although i did enjoy Halo 3's campain and custom games but i would go for reach and would recommend you buy the guide book if you get it its extrememly helpful
I am taking it the MW3 was a typo. I would have to say Halo Reach. The only two games i have are MW2 and Reach. When I first got Mw2 i was hooked on it, then I started playing reach again, and i find myself playing reach more than MW2. They are both great games, but I think Halo Reach is more fun! PS: But Mw2 is better than Black ops
call of duty is forsher a better game
Modern Warfare 2
Call of duty modern warfare 2 is better than socom because with modern warfare 2 you have better weapons and you run faster on the game. I agree it is way better!
Call of Duty Modern Warfare 2
Modern Warfare 2.
Halo Reach is better because you get to customize your own character and you get special get special abilities.
