Watched some survival gameplay for MW3, which that looks like it's could provide hours and hours of fun. I replayed MW2 again today I forgot that I really enjoyed that campaign. Sure it's over the top and scripted but over the top can be fun. Singleplayer wise I think I might benefit more from MW3 than BF3 but multiplayer wise I'm not excited for MW3 in anyway shape or form for MW3. I don't hate the multiplayer and I know for a fact once it releases I'll play the hell out of the multiplayer like I did with MW, MW2 and Blops but I just won't be as crazy about I was I was in the past.
I think MW3 will be good, not game of the year but at least worth the money (I just hope the campaign isn't 3 hours long).
