I'm posting this here because Nitronic Rush is one of the few games besides Overgrowth that has that feel of complete control over your character, in this case an awesome Tron-esque car. It's also developed by an independent company like Wolfire, which means it has the potential to be just as awesome as Overgrowth.
If you've never played it, Nitronic Rush is a free download at http://nitronic-rush.com/, I suggest trying it out, then consider donating to the kickstarter campaign, at the moment it has a long ways to go.
