I think adding some reality to the game would be cool, like sending out your pokemon whenever you please, training them however you want, being able to control the pokemon, But the DS is realitivly new to pokemon, and well, It really would take some time before they made a real big kick *** game, if they do manage real time that would be cool, but I wouldn't expect it so soon... You have to know limits... Not all systems and things can correspond things like trying to use a 3D system in a NES game, that just wouldn't go over well, whoo 3 pallets!!!!
But really look at all the awsome games that are out that have found the entire potential of the GameBoy, very impressive, even the DS it self is impressive, the first portable 3D system that has games that you can actually fully enjoy, But all I would really like to see in a future game would be.
More trainer pics and such like that, I am really tired of seeing the same types of trainers.
More variety in what you can catch in which game. Seriously especially in the US.
Actual ability to get serebii... without cheating in the US.
I would also like to see a good Day Night system again, that would be better in a game, and mabey cut the whole grassy areas idea, make it so you have to work to find the pokemon you want. I want something that hasn't been done before...
and oh yeah, mabey a large range for being able to battle and communicate and trade online, that would be cool, not to mention actual problems in the game that you needed to solve, and mabey more of a anime story type, like having to achieve something, not to mention a real pokemon leauge, fighting trainers and then moving to the eiltes, But how would fly work on this game? would you guide the pokemon to the town sorta like on DBZ legacy of goku II? XD
