Started playing MW2 SP last night.
My thoughts sofar. The AI is daft, not nearly as good as promoted. ON numerous occasions I would run in behind an enemy but he won't turn around to face me he keeps on shooting in the direction I was comming from. I even tested this by standing still behind a couple of enemies for up a to 30 seconds, he would just keep on reloading and firing in the same direction LOL. AI team mates are stupid, running blindly infront of enemy fire, also running right past an enemy, even Taking cover NEXT to an enemy a couple of times, with the enemy AI not even taking notice of the team mate :/
Weapons are a bit lol, as I found that a Single shot from a 9mm Pistol actually drops a person, I've just been running around using a pistol (when available) the whole time. I also love the fact that AI takes cover next to burning cars, and are completely oblivious to grenades landing right between their feet. The gameplay itself has a very cinematic feel to it and is very fast paced, but it's extremely over the top, but in a bad way if you ask me. While MW1 was leaning a bit more to the realism side, MW2 feels like it's steroid injected Hollywood stuntman in an over the top action movie little brother. I refer to the 9 billion feet Snowmobile jump.
I dunno, maybe I'm being a bit too sceptic about this, and I'm NOT saying that I am not enjoying it, but it just feels a bit synthetic, feels rushed :/
For me the SP (sofar) 7/10
