We at Hardcore Gamer love deals and free things, so when a free racing game becomes available, it's definitely worth noting. Ex-Digipen grads crafted Nitronic Rush to the delight of all who played it (and/or loved TRON and the San Francisco Rush series), and now the folks at Big Robot have released Permutation Racer - a free procedurally-generated racer that was finished up over the holidays. Unfortunately, due to having an iffy PC, we weren't able to test the game out - but it does seem to offer up some sort of gamepad support ala a bootup menu like fans of Sonic HD Remix would be familiar with.
