I guess a lot of people here like racing games but has anyone here tried TrackMania? It'll play on just about any PC and best of all there's a free version available . This isn't a demo or a time limited game. It comes with 65 tracks, Internet play, ladder system and uses a medal system for opening "locked" tracks. There's a track editor and more . The free version is called "TrackMania Nations Forever" and is available from here. I was amazed that this was being given away as the game play and graphics are superb.

There's also a commercial version called "TrackMania United Forever" that has a further 147 tracks with different types of tracks, snow, rally, desert, etc. plus there are thousands of user made tracks to download. They give you the free version to lure you into buying this but I can honestly say it's the best tenner I've ever spent on a game. The commercial version has World, Country and Region rankings and records, skinning of cars,etc, etc, lots to get your teeth into
