The first "Adventure style" sonic
game, released originally on the Sega Dreamcast. It was ported to the GameCube, X B O X Circle Edition,
PC (multiple times), and more I probably
don't care about enough to research about it. It's glitchy,
fun (when it wants to be), has a modding community, and can run on my computer (20-30fps in Minecraft let's go!!!!!). I got it for less than 4 dollars on steam once during a sale...
