Correction: Chaos Rings was previously released for Windows Phone, the game now has support for Windows Phone 8.0 devices. (Thanks Kimi!)
Square Enix is continuing to bring Chaos Rings to other devices. First released for iOS, the mobile RPG from Wild ARMs developer Media.Vision has been a sizable success that spawned a prequel and sequel. Chaos Rings was ported to Android and last month Square Enix released Chaos Rings for Vita.
You can get Chaos Rings for Windows Phone 7.5 and 8.0 too. Square Enix just released the Windows Phone version, which doesn’t make it immortal, but means there are more ports of Chaos Rings than Secret of Mana in the wild. Perhaps, Square Enix will give Chaos Rings a console or handheld follow up in the future?
