I don't race here but from my experience the game (2011) has so many glitches and bugs most peolpe are frustrated and disallusioned with it. High hopes for 2012 but with the online racing community being a minority sector don't hold your breath!
Good question!
some of the main problems:
The AI
The tyre wear bug (after the patch)
lack of corner cutting penalties
Online lag between drivers (what happens one one screen doesn't always happen on the other persons screen)
But, if you can get past all that, and join a great league where the guys follow the rules and drive cleanly like the one we have here, you can still have loads of fun with it.
Well, I think we're still good. Mods, setups and racing leagues are in the balance and, after all, we've surpassed the total number of both discussions and messages in the F1 2010 forum by far already.
Not sure what forum your looking at, but on the Xbox forum we are starting season 3 and we have four grids this season. Over twice as many players than season 2.
Credit to everyone there for making it what it is now.
