Quite a few if you look back in this thread.
Picked up Game stock car again. I just love this racing sim. It win no splendid visuals award but as a serious racing simulations it can get away with it. Good accurate tracks. Not to familiar with the south american racing scene so there is a lot of tracks to discover the secrets of.
Great selection of cars. Love the V8s and the F1 classic is a dream. F1 Reiza, F3000 and the Camaro is not bad either. I haven´t run the new mini much yet but that is always fun for funraces. Standing complaint is the AI of course. You can have some fun but nothing beats multiplayer with proper racers.
