The pokemon company will not make a game with all regions because the will loose money sense this game is going to relapse the other games that have other regions, like kanto, johto, sinnoh, hoenn even orre.(see my point)
My Mewtwo sense just came up with the thought that this could be a A Johto region game, however the mascots game to be Celebi. Since its has not been available in the U.S.A. (as far as i know). And i saw that there is a item(game) that falls from one of the ball during the show. I personally hope that its a Johto game i started playing Pokemon games with Ruby & Sapphire.
Its somewhat stupid that the ''PoKegod'' is at a 100 LV. This way you cannot get it at a level so you can personaly train it. It will take time before you restart the ds and do over again and again until you get it with the stats you want.Probably a few hours.
I really enjoyed both types but i prefer the mystery dungeon series more than the ranger because it has more than a few missions to accomplish and it keeps getting more fame and fans.
To tell the truth, i do not dislike the new site i like that everything is in one spot sort of. Its a new feeling that`s all. I think it is all for good.
