all games are not created equal

Gears of War 2's story mode takes the cake in this battle, but not by much. The cliche tough guy sci-fi marine type character is over done and annoying. The thing that won it for me is the length. CoD:W@W's was maybe 3-6 hours long depending on how you play.

Multiplayer, however, is where Call of Duty takes the win. Gears 2 is glitchy and the matchmaking idea was done terribly. The feel of CoD:W@W always played better in my eyes, Gears felt like you were running through mud, while CoD felt real, and overall more fun. The gameplay mechanics in CoD also helped it take the cake. The controls are much simpler, and the learning curve for online doesn't feel as steep. Plus, there's customization, that's always a plus.
