There were probably some before both The Lion King and Toejam & Earl but I just can't quite recall them. I've been playing video games since I was an infant. Those two were also for the Megadrive and not the Genesis since - as most people know - despite that they were the same systems, NA had the Sega Genesis while EU had the Sega Megadrive.
I still have both my Megadrive and Amiga laying around somewhere in storage. Never getting rid of them, even if they don't work. I also occasionally revisit Toejam & Earl through emulation. Same with the Micro Machines games.
