Final Fantasy Brave Exvius, which may or may not intentionally have an "XVI" in its title, launched today for iOS and Android. It's a free-to-play RPG with towns, NPCS, turn-based combat and an actual story I've poked around in Brave Exvius a bit and found it to be overwhelming albeit kinda fun. It's reminiscent of Final Fantasy Record Keeper in that it's one big remix of old-school Final Fantasy, complete with characters and monsters from all the old games. It's also got an energy system — once you run out of stamina, you have to either wait around or pay money to progress. That will undoubtedly be an instant turnoff for some, although you don't need to use any energy until you hit level five, so Brave Exvius gives you some time before it starts gating you off.
If you're into this sort of game and want to try Brave Exvius, I'd recommend using this helpful Reddit guide for new players. There's a lot of rerolling and optimisation you can do to get the best possible party. Also, if you sign up before July 17, you get a whole bunch of gifts — including Terra in Magitek Armour. Everyone loves Terra in Magitek Armour.
