No thanks, I don't want a different dev to make pokemon, because they probably would chance the battle system for worse, the problem with gamefreak is that they drop good innovations because they want every game to be unique, what they need to do is improve these new mechanics, I don't care about mmorpg, open world design, or action rpg, pokemon is one of the few games that is still turn based, not only that the formula can be expanded and improve, a different genre is not what I want.
I think that's their biggest flaw. That mindset of wanting to make every new game unique, instead of a continuation of what was already done and achieved till the previous title.
I think this mentality is what is preventing the games to have this feeling of evolution throughout the generations, because they're not continuing what they start on every game. All sorts of things, features, mechanics instead of improving, getting more detailed and enhanced, they just get cut and replaced by a whole new thingy. And this is in every aspect of the game, from the overworld, the mini games, online features, items, now the gyms, customization, etc.
That, along with wanting to release a new game every year, is what gives us situations like the unfinished Sun and Moon, followed by the true game US/UM that even modified the things, like story-wise, that people liked in the first installments.
Of course people will always complain no matter what, but I think Pokémon is one of the few franchises where its fanbase would be totally happy if it was more predictable and squared. What I mean is, things like not having a Pokémon Gray, or Pokémon Z, or not giving mega evolutions to all the starters, or not following the pattern of releasing a new mythical every year, or I don't know, adding new Pokémon mid-generation, those are things that prove Game Freak / Pokémon always want to keep "original", "surprising", "different" but at least I find that obnoxious. On paper that sounds nice, to have an unpredictable franchise full of surprises with every generation, but I think that works for every other game, but not Pokémon.
It works for Zelda or things like that to have a huge reinvention, or any other game that has just given us different kinds of experiences throughout the years. But Pokémon, the main series, are called "versions" so they should stick a bit more to the same formula, just enhanced, increased, up to the standards of the latest console / technologies.
