Open Sonic is a free open-source game based on the "Sonic the Hedgehog" universe. It introduces a different style of gameplay called cooperative play, in which it's possible to control 3 characters simultaneously. Unlike most similar games, Open Sonic provides a greater level of interaction between the player and the levels. It's more than just a jump'n'run; the user must come up with some strategy in order to get through the levels.

I had no idea this existed. Looks cool. A shame it won't run smoothly on the Dreamcast but maybe I'll give it a try on the PC.
*edit*
I watched a video and saw the Lost Vikings style gameplay. That is not simultaneous control of three characters since you can only control one character at a time. They need to correct their description.
