It’s strange STEAM is the only way you can obtain “Sonic 3 & Knuckles” officially nowadays, considering it was left off the recent Sega Genesis collection game, & Sega Mini console, and has yet to get an official Mobile or Switch release like Sonic 1&2 have.
I hear it’s due to legal issues with the Sonic 3 soundtrack, now that fans uncovered for sure the controversial Michael Jackson uncreditadly contributed to the game, and his collaborators are credited too, a few songs sound similar to his music.
I wonder if that wouldn’t be an issue, if the internet didn’t discover this, and fans therefore shot themselves in the foot, as this made the game impossible to rerelease in it’s original format.
