I'm not saying it as a bad thing, ripping off can be good. But anyway: Search and Destroy is pretty much just the bomb-plant gametype from CS, Gungame (obviously) started out as a mod for CS, Karachi was originally a CS map, a lot of the gun choices are similar to CS (Black Ops in particular), some of the map design is inspired by CS, and some of the desingners for CS went to work for IW, so I guess they re-used a few ideas when they joined IW. Again, I say this in no negative way, I'm quite glad they've been inspired by CS.
