Modern Warfare 3, Battlefield 3, or Saints Row 3?

Ok here's my plan...... Buy MW3 not cuz it's a better game but because it's way more popular and more of yur friends are likely to play...... But don't cast out BF3 because in the end that game will have way more feature and be awesome and a nice change from hours of Mw3 so buy MW3 first save up for BF3 and saints row is just a rent:p
