I'm not saying that we need to scrap everything, but the series really needs an overhaul. The pokedex is a mess and could benefit from a renumbering. Once gender differences were add there was no reason that Nidoran needed 2 entries anymore. The battle system is laughably out of date. I'm not saying to ditch turn based combat, though I would be fine with that, but you need to make it snappier. There is no reason you need to mash A so much between choosing your attacks.

I know none of these things necessarily need a reboot to be changed, but GF seems unwilling to actually clean up the series which is becoming more and more of a mess. Ideally this would have the old guard at GF stepping back and letting new blood take over. Get some actual fresh ideas in there instead of regurgitating the same exact game like they have for 25 years.
