As a big SEGA fan, this certainly has my attention. It seems the SEGA Mega Drive and Genesis Classics pack might be heading to Linux.
As seen here on SteamDB for a little more detail, Linux and Mac have both been added behind the scenes for Steam packaging. It's a good indicator someone is working on it, but of course it doesn't mean it's confirmed yet.
Featuring the entire set of SEGA Mega Drive / SEGA Genesis titles currently available on PC all housed within an authentic, era accurate, virtual space offering full controller support, save game functionality, local co-op (on supported titles) and Steam Workshop support.
From Sonic the Hedgehog to Ecco the Dolphin and Golden Axe to Alex Kidd, there’s something for everyone; whether you’re a SEGA Mega Drive / SEGA Genesis fan looking to indulge in some nostalgia or someone who’s never had a chance to play some of these gaming classics!
It's interesting, because SEGA are actually putting out this pack for Xbox One and PS4 which releases on May 29th, so perhaps this is to go along with it? Who knows, but it will be fun if it does happen.
