I actually just hit Prestige level 12 last night. I would definitely agree with you that Modern Warfare 1 & 2 are the cream of the crop as far as MP games go but as the crowds progress to the next game, I have to move along with them. (I don't really like Black Ops that much)
I guess getting into campaign-type games is a little too difficult for me as I don't have the budget to buy more than one or two games a year.
Speaking of the Modern Warfares/Infinity Ward group, don't expect another high level COD from Infinity Ward anytime soon. Did you hear about the West/Zampella walkout?
