I love this game! But on the other-hand its not that great i like playing it for 2 days then you just want to send it back. you will have fun playing it for a little while then you will get extremely bored... so make your decision on if you want to borrow the game.
Almost identical to the 3rd Forza. Many of the same tracks and cars. Gameplay is still very fun and lengthy, however I feel it was shorter than the 3rd. I didnt get too active in the online mode so I can't say too much about that other than there's online "groups" you can make with your friends and race other "groups" similar to a gang or something you could say. The game was very fun, definitely a good rent if you like realistic driving/racing. The cars were in incredible detail with a new feature to fully explore each car which is kinda cool. Rent it, you'll like it!
If you played Forza 3, you're probably not going to notice too much of a difference, but the game (as a stand alone) is still magnificent. The game looks gorgeous, has a huge collection of cars to customize, and beautiful tracks (same as in Forza 3). If you're a beginner you can allow the cars to brake for you, or you can turn off ABS and all assists and try to stay on the road. It's got everything for a car/racing lover, including the Top Gear UK test track. POWER!!!
