>>40136609Black and White's thing of having only new Pokemon until after you beat the champion was great and it's the one thing I'd really want that's actually somewhat believable
If we're really gonna get down to it, I'd for one like an actually different game that doesn't just have the same old stuff again, but beyond that though, the thing I'd want most is greater freedom of customization. The game letting you do as much as you want.
Be the kind of person you wanna be in the Pokemon world. Be a trainer! Or a breeder! Or a scientist! Or whatever! How about making your own gym with your own kind of looks and challenge and people and Pokemon? And you could get other people to try and take on your gym? Online functionality?
How about your team of Pokemon? What if you were able to have whatever Pokemon you wanted and not get beaten to a pulp in any serious battle? If you REALLY wanted to have a full team of Hoppip and be able to have at least a chance of standing up against the likes of Garchomp and Therian Landorus, you should be able to. It'd probably be one of those things that you'd really have to work for, but it should be possible, period.
On a similar note, what being a type specialist could end up being actually doable? Like, having Pokemon with the same type gives a boost in some way? Then you'd REALLY be able to pull of being a traditional gym leader!
I dunno. These are just ideas.
