Things I'd like currently;
- A place of your own you can decorate yourself. I earlier said secret bases should return, which I would love, but I think I should go less radical and just say there is one location and you can customize it to make it your own, that is much more plausible... On a less likely note, I think we should be able to alter the exterior and the potential garden, just like you could change the safari zone, but with more options. The decorate function for pokemon amie hints at something, but probably it is just the background or the pokemon.
- Again the return of ball capsules, can't stress it enough... I miss my dramatic entries... Just remove the letters and add more effects.
- Something like the PWT, but with the elite-four members, frontier brains, and new special trainers included. I loved it in BW2, it was easily the best battle frontier like facility in since Emerald's in my opinion. Actually, maybe they could make it part of something like the battle frontier in Emerald? Also, all the possibilities for amazing buildings in such facilities.
- The addition of substantially satisfying side quests. My main problem with series is the relatively large lack of deeper and more intriguing side-plots and for some reason that really bothers me. Besides the fact that such a thing would make pokemon stronger as a series on this side of the world, as in pokemon is still very much a JRPG, but they could add WRPG elements, such as enormous non main story side-plots and especially many side-plots (There are also JRPG's that have this, but I now use traditional WRPGs, that almost always have it). Deeper side-plots also allow for new kinds of areas and strong trainers they could not add before in one game. There should be one or two side-plots before the first time you can defeat the league, even more (3 or 4) after the first time, with a large postgame, and if you defeat the league the second time you get the last few. They could easily make the last for more than a hundred hours, just to complete it. Of course if you're finished there should still be enough to do, like the battle frontier I mentioned earlier.
Side plots are there already, but it still needs a lot of improving in my opinion.
-Planting berries in the overworld... words can't express how much I hate the DW for taking away that function... I would like it if they return it... not in the UFO pots, but good ol' RSE and DPP style berry plants in the overworld. I don't have much hope for it to ever return, just like secret bases, but still... I want it back.
-Hard mode from the beginning and a more challenging game in general...
-Large and extensive main story (with more than 8 gyms...)
