I have recently decided to find as many good free games as possible, luckily my search for a good site was short. DigiPen
is a fantastic site for such games.
One of the more recent games I have played from them is Nitronic Rush
which went on to create their own site for the game separate from digipen.
I found Nitronic Rush to be a great game, but the fact that I find Tron to be fantastic might have something to do with that.
I though I would share this information and ask the community to share any information or ideas of their own relating to low cost good gaming ideas and sources.
