That depends on what you think
From the game marketplace
Sonic is a terrible game no matter the console its being played on.
Yeah, the 20th Anniversary Sonic game called Sonic Generations will be on it and also Xbox 360.
i have played the game on xbox an wii but no silver
Sonic Generations was not released on the DSI. It is a PS3, Xbox 360, PC and 3DS game
You can be super sonic on the final boss boss for ps3, ps2,wii, and xbox 360
There is a new game for it and it's only for the XBOX 360 kinect. The game is called Sonic Free Riders, you can be avatars in there.
Xbox 360 and playstation 3
Not really, Sonic Unleashed was on xbox 360, wii, and some other consoles. An old sonic would be on a cartridge but Sonic Unleashed was on a disc, so it's not that old. 2008 was when it came out, but no Sonic Unleashed is not an old sonic game.
Well my two personal faves are, Sonic the hedgehog 2 for the SEGA Genesis and Sonic Adventure 2 Battle for Gamecube.
The only way to do this is to hack the game console. Check out some you-tube videos on how to do that.
