I recently tried out the first Yo-Kai Watch game, out of curiosity for what the rest of the mons scene is doing.
My most important takeaway is that anyone who says Yo-Kai Watch is trying to copy or replace Pokemon has clearly not only never played the game but never played any other mons game either and probably thinks Pokemon has a copyright on the genre. The two franchises share a target audience, but otherwise they could not be more different. Yokai talk and are presented as distinct characters, yokai cannot be commanded, and most shockingly of all, the protagonist isn’t silent!
As for the game itself, it is a godawful grindy mess that can barely be called a game. But it has some interesting ideas, and I enjoyed the creature designs.
