Keep it PGOriginally I thought mega-game sounded like great idea, because there was so much potential that could happen if such a game was created and successful, just by its concept alone.
Then I realized that unless they put a particular spin on the game, it would essentially just end up being the same game over the same Generations with nothing particularly interesting that happens.
Plus, a Mega-game, where you essentially travel to every location and every region, essentially ruins the ability for GameFreak and Nintendo to possibly release remakes of the older versions people seem to want, and they probably won't give up that opportunity until possibly the Diamond/Pearl remakes occur.
The Pokemon games in my opinion should be branching out more into different ideas and aesthetics perhaps with a twisted setting on the regular games.
Perhaps, instead of a brand new region, you were in an Unknown region in a very large building, unknown on how you got there and then.
Instead of living, breathing Pokemon, all of them essentially are robotic or something along those lines, and you are essentially in a mirage that the building plays on you, thinking you are in some region with other, real people.
Essentially someone kidnaps you and other people and pit you together in some giant factory with robotic pokemon or whatever!... Not a fully fleshed out idea yet.
Or, as I always say now-a-days, the best, "Normal", Pokemon game will be when your MOTHER is actually the Champion all along, secretly following you in different disguises along the way, following your progress until you make it to the league, finally making herself known.
Because really, we always see our "mother" in-game just sit at home, and really only just heal up our Pokemon and we never really see her again.
They already made a Father-figure with Norman in Hoenn, what not have a Champion Mother?
There are so many ideas Pokemon could slip in/out of. Look at the Mystery Dungeon series, they created that where YOU are the Pokemon. Seems like a great idea.
The Pokemon Ranger series isn't as interesting, but I guess is alright for what they are.
Anyways... Off-topic from the idea of talking but X/Y... but oh well. xP
