The sounds: Old re-edited sounds from the previous games. Especially whenever you shoot metal.
Decals: Old decals, used in their other games.
Story: As with every game that is majorly overrated, terrorists, Russians, and nukes.
Every character felt out of place. There was no real emotional connection with the characters, thus you didn't feel bad at the end. Though I did wonder the fate of Captain Price, it really doesn't bother me or not whether he's in Modern Warfare 2.
As for multiplayer...it's average. It's basically like Counter-Strike and its derivatives, fun to play, but no real team work or challenge is present.
You guys are simply calling it a great game since it sold a lot, but if you REALLY take the time to look at it, it's an average FPS.
