I think that this is a great idea I would love it if Pokemon Z would go global it would give Pokemon a boost to go higher than they have never before.
Creating places where different kind of Pokemon could live, that would be awesome. Going to Australia or Africa and seeing what kind of region they could make there. It would be more adventurous exploring different places and routes that would have new Pokemon that would you would catch and raise to become strong.
Pokemon Z would be an awesome game if this happened and I'm sure that millions of people all over the world would buy this to try it out for themselves.
I really hope that this happens and if so awesome.
