yea, Modern Warfare thus far has been the high point of the series. Holy balls was MW good.
And actually, iirc that wasn't Chernobyl exactly, it was Pripyat. Compare the pictures from the op here
http://www.nextgenboards.com/vb/general-talk/8215-a-map-in-real-life.html and that level of COD4, especially the fairgrounds. Holy crap.
Modern Warfare 2 on the other hand... sucked. HARD.
and that trash of multiplayer, luckily I haven't had any issues with Blops multi.
Some of that could be the change in format (360 -> PS3), not trying to start a console war, just my thoughts.
EDIT: I just noticed that what I intended to be a progression arrow looked like an opinion of console superiority. Ooops.
