New games with amazing graphics are cool and all, but nothing beats playing classic Sega games. Of course there have been ways of playing them through emulators and such for years now, however Sega have now made a number of titles free to play (with ads) on both Android and iOS mobile devices. That means you can play anywhere! and more games are coming too!
Games available so far:
Sonic the Hedgehog
Phantasy Star II
Download them now and have a jam or head over to Sega Forever for more info!
