My predictions on the next game...hmm...
1. It would be cool if the name had to do with the elements of nature, i know they did fire red, leaf green and so on, but maybe something like "Pokemon Sky" or "Pokemon Earth" or maybe "Pokemon Twilight gray" or something
2. For mascots I think it would be rad to see them do something more with Zorua and Zorraock(sp?) maybe name the game "Pokemon Shadows" or "Pokemon Oblivion" and have the mascot be Zorua/its evolved form or use a pokemon that could literatly destroy the entire world which would make the name "Pokemon Oblivion" be cool of have a pokemon be the mascot that can control light and darkness sense Resham and Zekrom represent good and evil and not really light and darkness?
3. The story line should have two different branches that you could take, early in the beginning of the game and throughout it you should be put up against two answers to a questions, one that sways you into becoming evil, and one that sways you into becoming good, while your rival takes the opposite path. like if you choose to be part of the evil team, your rival will become good and try to stop you, and at some point you can either choose to over throw the evil team's leader and become the leader yourself, or not and watch as your leader is beaten by your rival, or team up with your rival to stop their plans.
of course you'll get more then one chance to switch back to either the good or bad side,and you'll be able to wear different clothes depending on which side you choose, bad side= evil team's uniform and good side=your default good person clothes.
also it would be cool if depending on which side you choose, the out come legendary you get differs, which would mean that the game developers would only have to really make one game, unless they want to have two games, one with you playing as a girl, and one with you playing as a boy. and maybe have it so that you have to save the world literatly, and go to different regions of the world, helping to keep the ballance of it.
4. If the new game was more like a continuation of BW's storyline, i would very much love it if you'd be able to see N again, and if its the same gym leaders, have them look older, and the really old ones (Like the old dragon master/dragon gym leader in BW) die and have either new ones or their children be gym leaders.
5. I just had a brain blast...what if, instead of like having a pokemon game where EVERY person in the game just LOVES pokemon, what if they made it so that the people have forgotten about their dreams of being pokemon trainers, and rather went for having lives much like ours in our world? like being pokemon trainer is going out of fashion, and you have to some how revive it...
Or maybe the complete opposite, and instead of having a world in the way future where being a pokemon trainer is looked down upon, maybe have a game where its in the far past, like in the pokemon movie "Arceus and the jewel of life" the part where they went into the past? where there was no pokeballs, and pokemon were treated as well...slaves rather then partners? and maybe you'd be a person who thinks of pokemon as being partners rather then tools...and you have to change every one you meet that pokemon should be partners, and like, you end up sparking the pokemon trainers revolution...evolving into the games we love today...i think it "Pokemon: Origins" or "Pokemon The Beginning" would be a good name for it...
I should really stop now XD or else I'd be thinking up Idea's forever! XD
