As of this writing, I am at the tail end of completing Yo-Kai Watch...or at least, the post-game stuff. Not gonna be able to get all the Yo-Kai, though. Not in a million years...
I must say, this game really blew my expectations away. I mean, the method of going about getting Yo-Kai is certainly different (though can be a slight be RNG-based at times), and the battle system is really fun to utilize, especially against the more challenging enemies this game has to offer...and this game can get pretty challenging at times, even with the over-abundance of EXP I had gotten over the course of the game.
The one thing that really amazed me? How much exploration it had. Seriously, I could go for hours just exploring a new map before progressing the story, which is...relatively short, and while not exactly plot-heavy...I would say it's more than enough for its type of game. Just the sheer feeling of looking over every nook and cranny this game had to offer, looking for new Yo-Kai, or treasures...I'd say that feeling of exploration was definitely something I enjoyed the most.
Also Chilhuahua is my new bae and nobody can convince me otherwise
