Sega Ages is a label made by Sega used for ports, re-releases or even enhanced versions of their own old games. However, in the VGM scene, you can search for:
- The Sega Saturn version of Sega Ages, which consisted in accurate ports of Arcade games and partial emulation of Sega Master System and Sega Mega Drive games;
- A early-2000 mobile version of Sega Ages for Japanese cell phones, which are a trending before the J2ME-enabled cell phones was a thing all over the world. Many of those games are actually downgraded ports of old games split in 2 or 3 parts, and all music on them was a questionable MIDI-quality;
- The Sony PlayStation 2 version of Sega Ages, labelled Sega Ages 2500 in Japan, which consisted of 3D remakes and emulated compilations of old Sega games. Some of earlier titles did come into USA and Europe, under the name Sega Classics Collection;
- The Sony PlayStation 3 and Xbox 360 versions of Sega Ages, labelled Sega Ages Online in Japan and Sega Vintage Collection elsewhere;
- The Nintendo Switch version of Sega Ages, which consists in enhanced versions (similar to Sega 3D Classics on Nintendo 3DS, also done by M2) of several Arcade, Sega Master System and Sega Mega Drive games, starting from Summer 2018 (Winter 2018 if you live in the Southern Hemisphere).
A similar service called Sega Forever exists for iOS and Android smartphones, which consists in re-releasing old Sega titles for their past consoles and mobile games for free, but with advertising all scattered through the game(s) (buying for their removal is optional).
