For anyone with email problems don't use hotmail, gmail or any of those type of web based email addresses. There will be a long delay and you may not even get a email to register your account.
I think the game is very good like everyone says it's free so how can it be bad.
Well there are a few problems but nothing to stop you having fun. Plus they are fixing the server problems where you keep getting kicked out of the session after the time is up. This is if you are online doing the comp, single player works fine.
The only problem with single player I have found so far is the old Race 06 (yes Race 06:confused:) bug. When the racing is over you have to wait for the rest of the field to finish before the continue with highlight. You can then click it to continue. Most people have thought the game had crashed but it's a very old bug.
My favorite cars are the S40, C30 and 850. The 240 is a lot of fun for drifting just hate to race with it. :p
