Well I was in two minds as to whether I should break the seal and install the game.
I have.
If you liked MW2, you'll like this. If you didn't you won't.
I've played 3 rounds of MP, I got even K/D in the first two and then realised how the Killstreaks worked and got 25-4 in my third round.
The game runs at 90fps maxed out, doesn't look any different to MW2, so I don't know what those advanced options do. But the graphics are ok and the gameplay is as unchanged as it's been for the other 7 games.
Then again I wasn't expecting anything else.
Mine cost me £16, effectively, after I sold the PSU it came free with.
