This really isn't an opinion topic. It's a fact. Battlefield 3 is a better game than Modern Warfare 3. And if it weren't for Skyrim, Battlefield 3 would be the game of the year.
Here's a fun fact for you. Anyone who tries to pass off an opinion as fact is an idiot. I do believe Skyrim will win GoTY, but Battlefield would not win if there were no Skyrim, and I am not saying MW3 would win.
