I'm about to post a crazy opinion:
I like MW3's single player more than its multi-player. Like, I'm actually enjoying it, its one of the reasons I haven't ditched it yet for BF3.
Also, I know so many people hate on CoD, so I'll go out of my way to say congrats, Activision is clearly doing something right.
