Sega has started to release free mobile versions of classic games from its older catalogue.
The first five are available now via the Apple and Android app stores.
Its been planned to release additional titles every two weeks for the Sega service.
Some fans have complained about the first releases, saying Sega has done a poor job of converting the classic games to mobile devices.
It’s about allowing fans to reconnect with past experiences and it’s a very easy conversion to take those games to free.
Like other apps, Sega said it would run ads before and after the games were played, but it said it would make it easy for players to avoid them.
The online gaming catalogue will feature titles from all the Sega eras.
The first five games on Sega Forever are:
Sonic the Hedgehog
Phantasy Star II
Games can be played via device’s touchscreen or by a controller. Sega said they would also be playable offline but people can save their progress online. The games may have a multiplayer option to many of the games.
But not all fans of older games were happy with the arrival of Sega Forever.
