It's a good game.
Handling feels like GTR with some controls that step in and prevent it from getting out of hand.. so not as nice as GTR:Evo but a significant improvement on previous NFS games and others like Grid. The main problem is lack of decent controller setups - and not that many options to adjust yourself. Once you do get a good setup though it's perfectly possible to drive the cars without sliding them which is more rewarding (and faster).
You can't simply boost power without consequences either - downforce and tyres need to be upgraded or it's very easy to slide again, and they've added slipping clutches so there's a need to upgrade the drivetrain as well.
Multiplayer is both the game's biggest strength and it's weakness - underneath it's a really sound game, but there's very little choice in how you join games - it randomly chooses a lobby to send you to, which is frustrating. As is the enforced start of the match 2 minutes after the second person joins the lobby.
There are some bugs, of course, like car setups disappearing or worse, setting themselves completely wrongly, but the game is very stable.
AI acts like the majority of players you meet online, which is to say, very rudely. Can be frustrating when you're trying to race cleanly but other players or the AI want to play bumper cars. Best recommendation is to get some friends who you know race cleanly, then try and get together with them for races.. but with the multiplayer setup that's easier said than done!
Graphically it gives a wonderful sense of speed with all the track objects hurtling past you and the blurring effects, but some aspects aren't as pretty as Grid.. that said you won't be taking the time to notice in a close race, or even just some of the faster cars as they demand a lot of concentration!
