Make sure you try to get both Toejam & Earl games, although diehards will swear the 1st one is better than the 2nd one. I also recommend the Batman & Robin side scrolling beat em up, not only was it fun but it had a banger soundtrack.

I’m not certain if you got the version compatible with the Sega CD but if you can locate one there were several ports of Genesis games to it. Eternal Champions was better on it because it had actual CGI and better animations, the Batman game was baller and, of course, there was Sonic CD as well.
