For a SIM racer you can't really ask for more. The ability to customize your car too look the way you want it to is awesome and the uploaded community designs and tunes are great as well. The only thing really lacking is that there are not enough tracks and they really want you spend money on the cars that are really cool.
I held on to this game for quite a while. I'm not a big race game fan. I find the games very repetitive. This is still true with Forza Motorsport 5, however, the game does have a lot of potential; especially by incorporating drivatars. Unfortunately, driving around with drivatars still feels like I'm competing against AI rather than a real human being. With all this said, one thing is absolutely certain; the visuals are stunning. The reflection from the cars and the amount of detail from the interiors are so great that you'll think you're driving a real car on a TV. I was very disappointed by the lack of maps though. I felt like I played the same 8-10 maps over and over again. I would love to have seen twice as many maps.
