Well it is very good. On hardcore with G27 is pretty realistic. If you can use your wheel on the PS3 as well then it is worth getting simply because more people will use it than the PC version.
give it a month before it is ruined. At least with the mk1 MX5 I plan to get for a first car I can get away with it as it is a cheap car (as in banger prices) the R35 will be vandalised so quickly.
Tried the beta. From what I saw it was better gfx than TDU. No more stupid roads which made you fly away. Cars drove looked and sounded better. And the online quite stable.
