With Youkai Watch becoming a massive hit in Japan, even giving Pokemon a run for its money, I'm sure YW will be pushed as mush as Nintendo/Level 5 possibly can.  In terms of sales, the 3DS has sold better in NA. Europe, on the other hand, has a better track on games aimed at younger audiences, at least on the 3DS (Lego games, Tomodachi Life, Animal Crossing, and Level 5's own Prof. Layton). Where will Youkai Watch become more popular, Europe or NA? Or will it fail to live up to a fraction of its japanese success in both markets?

EDIT:

Here we have the opening week for Youkai Watch in the US. I'll post the european opening when it comes out.

usually i would say europe so ill say europe

Europe is my guess.

I think the french will eat this shit up

America

America. won't be that big like Pokemon but it would sell better in the US than Europe.

To be honest, I don' think Yokai Watch will catch on anywhere else.. : /

Just watched a episode. Not a fan, not a fan of Pokemon either. I think I'm just too old for it. I live in usa. LOL. Yall are talking about a game? Sorry was talking about a episode on tv.

Europe

My guess is that it'll do better in America, but NoA is still hilariously bad at getting these sorts of things out - at least NoE has an official anime channel.

In fact, I'd wager that in the absence of any mainline Pokémon game this year, NoE will do a better job with the advertising, but more in America will get to view the anime.

So, Europe it is.

But, please do note: This is relative to hoe large the install base is in Europe.

Pokémon games are boring, repetitive and run poorly. The first two generations were amazing because things were still fresh, now it's so fucking stale. I doubt you even played a YW game...

And lol at the "maybe" aesthetics part, YW games look a lot better, there's no doubt about that. The aliasing in Pokémon is some of the worst on the 3DS. The battle system is a complete borefest of spamming the same attack over and over again in SP. There's no strategy or tactics involved at all and the story is horrible.

Quality has little to do with sales in most cases.
