A great themed emulator that contained a lot of mega drive/genesis games that aren't really available legally elsewhere. With built in ability for mods, fan games, and even other mega drive games makes it quite a good base that should've been built on to include dreamcast. These games shouldn't be locked to a subscription service, and I'd hope a Gog version could have the ability to mod in games much like the steam version. Long shot but maybe a way to add in mega drive and genesis games as they get added to Gog to put them in one collection.
