COD World at War reigns supreme because its campaign was coop. This alone makes it the best.
I never got into COD 4 for as long as the others since so I think it is overrated.
Modern Warefare two was better than 4, for the campaign and online, but withut a coop campaign it fails.
I am In no hurry to get Black OPs because I will never buy an Activision game new, (fuck their philosophy) but I know with =out a coop campaign it will never be better than world at war.
Edit: bought black ops it is great but I am yet to play the campaign and since there is no coop it still cannot beat World at war.
