So, Sonic Christmas 2011 is one of those weird little holiday romhacks for the Genesis—basically a festive reskin of the original Sonic. You’re still speeding through Green Hill Zone, but now everything’s covered in snow, and Sonic’s got a Santa hat. Classic tunes get a jingle bell remix, and even the badniks look like they raided a Christmas decoration box.

It’s short, obviously—just a seasonal novelty—but there’s something charming about bouncing off snowmen instead of palm trees. If you’ve played the original to death, this is a fun little distraction for a December afternoon. Just don’t expect a full game.
