chautemoc: Might as well wait for World, which is free and has only online MP if I understand correctly.
Hmm, sounds like they are taking the Nadeo/TrackMania approach - give base game away for free, then charge for extras/DLC. If you haven't tried TrackMania, I recommend it. It is less free form racing and more start to finish track racing, although some of the tracks are a bit 'tricky' to say the least. Physics in the game is top-notch, also. It is pretty playable from the keyboard - driving wheel/pedals not required.
I found out about it via the open source game ManiaDrive, which I found about while testing UltimateStunts, itself a clone of Br0derbund's Stunts.
Who owns the IP to Br0derbund/Mindscape now?
