I popped it in last night and was about to just play a few multiplayer matches but when I selected MP it said "we strongly suggest you play campaign first" so I figured that was probably a good idea. I've played through campaign in the last 2 games before going to MP but after seeing the MP videos I've been so pumped to jump into Multiplayer! I'm sure campaign will fly by - they always have pretty good stories and this one seems great so far. Been waiting for this day for a long time! This is definitely my most anticipated game of the year and so far, I'm not disappointed and I've barely played a couple hours. I know a lot of people skipped WAW but I loved it. I played the shit out of it. It's very refreshing to go back to the modern weapons/style though. The last one was a nice change up too... Have fun guys!
