My favorite PC game of all time was Interstate '76. It was really unique in its gameplay and has the best soundtrack for a game ever, featuring 70's funk, where I would pop in the cd on my computer just to play the music. I've never done that with any other game, before that or since (the site has archived the soundtrack and you can download the mp3 files from there). Later, I'd find out that there were some really heavy hitters who were a part of the soundtrack. In January 2007, I started searching out more recent games that were similar in gameplay- where you are an auto vigilante, completing missions in your weapon-infused, tricked-out vehicle (but that ran on Linux). Lo and behold, I came across such a game in Interstate Outlaws.
