Nostalgia is a powerful thing and it seems that Sega finally realise that too. With the Sega Forever service people are able to download and play classic Sega games for FREE on their Apple and Android devices. The games are free to play (including offline) but will feature adverts, so to turn off the adverts you have to pay a small fee. However the possibilities of playing these games on the go and with modern features like cloud saves, Bluetooth controller support, and online leaderboards putting up with a few adverts doesn't seem so bad. Currently there are five games including: Sonic the Hedgehog (the original, not the god-awful 360 game, Comix Zone, Altered Beast, Kid Chameleon, and Phantasy Star II.
Sega have promised that this list will grow and that the service will not just feature games from the Genesis or Master System era but also may include Saturn and Dreamcast games. The possibility of playing Panzer Dragoon, Wonderboy IV or Streets of Rage II on the move sounds great.
