This is an advert for any passionate gamer's, or people struck with boredom. Its a game based on the light cycle sequence from the original tron movie. (is anyone feeling nostalgia right now ) Its open source and has a very dedicated group of core players, that are constantly updating and improving the game. The single player features are highly limited and are ultimately useless until you get a grasp on the customization available to exploit them. But the multiplayer features are in effect endless. There are many different game modes such as fortress, ctf, racing, dogfight... with more being developed and servers introduced regularly. The graphics are minimalist but don't be put off by this. The high customization abilities and pure skill needed make the game a very challenging one to master. There is a decent competitive scene with various tournaments regularly each month.
If your at all interested to try something new on that rainy day where there is nothing else to do then please download the game, come to the forums, and become addicted like myself.
