I do have Genesis games actually. Because I was running out of real estate, I was unable to display them, so I left them at my parent's house until recently when my mom was talking about having a yardsale, and I will be damned if some VG collector snatches my childhood memories for a few measly dollars.
The games that got cut off that are next to Sonic 3 are Sonic & Knuckles, and Knuckles Chaotix
I had a couple more, but my brother lent a bunch of them out to his friend a couple of years back and I never seen them again (Sonic 2, World of Illusion, Streets of Rage 3, Dinosaurs for Hire, Golden Axe, NBA Jam, Contra: Hard Corps, Revenge of Shinobi off the top of my head).
