I am a massive Forza 3 and Gran Turismo fan, so will soon be purchasing the Logitech G25 racing wheel to use with the games, but they're not out for a few months yet. So in that time, i need some reccomendations of semi-realistic racing games for the PC. Or ones that are just fun to play with. It's a large gap in my knowledge of games I don't really know any racing games..
