Good news, RPG fans. The iOS port of the classic '80s RPG Lunar: Silver Star Story was recently updated to support 64-bit devices, sparing it from the list of games and apps that no longer function in iOS 11.
Lunar SSST has been well cared for since its iOS launch in 200x, receiving numerous substantial updates. Over the past several years, SoMoGa, the developers in charge of the port, have re-drawn the graphics in HD, enabled iCloud save data syncing, added additional language translations, programmed support for every new iPhone screen size, and - of course - added controller support for the Gamevice. It would have been surprising if Lunar was abandoned in the transition to 64-bit-only apps - luckily, it wasn't.
If you're an RPG fan who somehow missed out on Lunar SSST in the past, now is a great time to catch up on a classic.
