13 Sentinels is the newest game by Vanillaware, creators of Muramasa, Dragon's Crown, Odin's Sphere and a lot of *chef kiss* design, they moved away from high fantasy to make a robot game and it was announced forever ago and we still have no release date (fall 2019, but who knows!!)
If you are interested in playing it early, there's a demo available right now on the japanese psn store
also port the other games to newer systems, you are missing muramasa!
