Inevitable comparison for me, I didn't want to play a Pokémon game at the time cause of all their cons.
Yokai Watch doesn't have the cons of Pokémon: lack of story, grinding... but has others: boring combats, shit befriending system.
The combat system isn't really bad, but once you understand all its possibilities, you also understand that to take advantage of them you're gonna need to grind befriending yokais, bug catching and fishing to exchange with rare objects and it's boooring.
Stupid sidequests.
It has all the charm of a Level 5 game.
