A little different from the rest of the JRPGs on our list, Stoneshard: Prologue isn't exactly a JRPG. Instead, it's more like a turn-based version of Diablo with a hint of Darkest Dungeon thrown in for good measure.
NES, SNES, and Genesis fanatics will still want to make a point of checking out the Stoneshard demo anyway. The game's turn-based combat, classic pixel-art style, dungeon exploration, and dark take on magic and religion will strongly appeal to JRPG fans.
Right now, the short Prologue version is up for grabs for free, while Stoneshard itself launches in Early Access this coming February. I suspect it will turn some serious heads when it's finally finished.
