I am currently waiting for all of my Sega Saturn stuff to come in.

Outside of that I have been playing a lot of the better Genesis Sonic Hacks.

-Sonic 2 Heroes
-Sonic3 & Knuckles: The Challenges
-Sonic 2 Retro Remix
-Sonic The Lost Worlds
-The S Factor
-Sonic Megamix

All fun games that I would highly suggest if your a fan of the series.
