Following the console release of Sega Mega Drive/Genesis Classics, SEGA has quietly released the collection to Linux and Mac. The game is also available for Windows. The collection features the same features as the console releases, meaning the new multiplayer and challenge modes have been added. Interestingly, this version features more games than the console release. Most notable is the inclusion of Sonic 3 & Knuckles, though it is unknown if the games are available without lock-on. Also included are the three Ecco games, Eternal Champions and Sonic CD. The inclusion of these games are one major drawback to the console release, and it’s nice to see them included here though it does call into question what legal stipulations are holding back these games on home console.
UPDATE: I installed the hub on my Mac and it runs smoothly however it looks like Sonic CD is Windows only and launches separately as it has in the past. It does not appear within the collection.
