I had just noticed that NES is in free tier now (I clicked on Mario 2 USA by accident, and was scared/surprised lmao), and was hoping maybe Genesis could make the leap too, because I've got a mean hankering for some Genesis versions of SNES games
(I was also gonna suggest making the other Sega Consoles free too, but A. That might be pushing it some, and B. There's gotta be SOME incentive for higher tiers, right?)
