cod4 was excellent, played the MP for many an hour
mw2 was ok, but I felt a little dissapionted with the purchase, mp was ok but only in a chasing the dragon for unlocks style
black ops was terrible, felt ripped off, bits of the single player were excellent, bits not so good, the multiplayer I found to be a POS, people warping / glitching around the map like im playing on a 56k modem, also think about this time I became bored of the "spawn / kill someone / get shot in the back by the guy I just killed who just spawned behind me" gameplay about the same point, it only encourages the base fps gameplay of run / spam which I dont really enjoy and doesnt involve any real skill
avoided mw3 completely, and didnt miss it at all
this looks.... bad, graphics are not great, concept seems poor, and I know the gameplay will just be the same old spam and run
