I've never played an F1 game. I just started watching F1 this summer so I think I'm going to buy the game so I can get a better understanding of the sport.
F1:2010 seems to include the full rule set for the 2010 season.
I think you will have to select the hardest difficulty settings to get the full experience though.
Be sure to post up what you think about the game, come release day.
