This whole package is done by D3T Limited with no association to M2 – so this release is wholly unrelated to the ongoing SEGA Ages project as well as the 3D Classics collection on the 3DS. This release presents the original Mega Drive games emulated as they were originally, with only small cosmetic changes as well as external manipulation such as save states. SEGA has been one of the more proactive companies regarding re-releases, so it can be confusing to think of how everything fits together. The total collection rounds out at a staggering 51 games. The Switch release contains every game available on those volumes (except Sonic 3 & Knuckles, two Wonder Boy titles and the Ecco the Dolphin trilogy – all victims of copyright issues, sadly) as well as some bonus features such as fast-forward and rewinding of gameplay, save states and online multiplayer.

On Steam, you can buy “volumes” of around eight titles apiece, which would get added to the hub. The original “game hub” design originated through SEGA’s Mega Drive re-releases on Steam, which a few years ago implemented an overarching framework to allow for cross-game achievements and customisation. To clarify, SEGA Mega Drive Classics Collection (or Genesis Classics Collection in the US) is a port of a port. Related reading: Our review of the collection on PlayStation 4)
