Bought the game last week, finished the single player campaign a couple of days ago. It plays more like being in a film than a game, which for me is great, as a cinematic experience it is superb, the game play is better than any other game I have played before (which doesn’t say much really - have been out of touch of the FPS market over the past few years).
The multiplayer is great fun too. I had some initial issues connecting in the first place due to PunkBuster connect issues, resolved them by updating PunkBuster manualy with PBSetup.exe then running the game as Administrator under Vista 64.
All in all, great game - well worth the spend, and brought a lot of enjoyment to my Christmas.
