This 4K 'Sonic Adventure' remaster is entirely fan-made

It's a game made in a game about making games.

If you’re dying to play a new 3D Sonic game, we’ve got good and bad news. The good news is, you can play this very cool-looking one right now! That bad news is, you can only play it by not actually buying a new Sonic game.

This very convincing looking 3D Sonic adventure, highlighted by TheGamer this week, was made by two enterprising fans using PlayStation’s Dreams game creation system —a sandbox-style game about making games that has yielded some sophisticated and wildly creative results.
