As someone who grew up in Japan around the time of Pokemon Green/Red release and watched the subsequent explosion of popularity, Yokai Watch is the real deal and will be absolutely massive around the world. I recently beat both games and really loved both (especially YW2). Get hype people (and heavily invest in first edition merch).
I thought that the second one improves a lot over the first one? And that you can jump directly to the second without playing the first? If that's the case I'll get the second one (even if there's a third one coming )
