K, everyone knows that Halo 3 is a long waited trilogy, but COD 4 has awesome first person shooter and live. Here, you get to vote which one is best and why. Example:
Halo 3 because of action.
You get the point. Personally i like COD 4 but i haven't tried Halo 3. I had a tough decision on what game to buy. If your thinking of buying one of them, try renting game first, try it out, and maybe buy. If you can't rent, ask friends or look at reviews. I'll be taking a percentage on votes. Start voting!
Wow that's a hard question. I gotta say Halo 3 though. I haven't played COD4 much, but I'm a big fan of the Halo Trilogy. Plus, there's something about killing aliens that fills my heart with gladness.
