What kind of game would you want after Legends Z-A and why?

unlikely

I want PokePark 3. If you've even read any of my posts, you know why.

As I look at each Generation respectively, here's how I view things.

Generation 1: Has been remade twice. Firstly, with FireRed/LeafGreen for Red/Blue while Yellow got Let's GO Pikachu/Eevee, the latter of which introduced Fairies to Kanto while also shoring up is regional Dex that lacks Dark/Steel/Dragon with Alolan variants. Could Gen 1 get another remake in the future? Eh possibly, although that's highly unlikely given Let's GO gave Kanto a Gen 6+ update.

Generation 2: Has only been remade once with HeartGold/SoulSilver. Does it deserve another remaster? Emphatically yes but only if they give Johto the proper respect it deserves. Fairies and Mega Evolutions(Mega Ampharos!!) deserve to come to Johto but only if they do it right. BDSP does not give me much confidence but here's to hoping as they say.

Generation 3: Got remade once with OmegaRuby/AlphaSapphire. Does it deserve an update? As of now, it's a no, but who knows if that will change in the future.

Generation 4: Recently got updated with Brilliant Diamond/Shining Pearl and honestly this region deserves a massive mulligan. Even if it's one game based on Platinum, this region deserves a 2nd chance. BDSP did some things right like with Gym Leaders and especially Elite 4/Champion but outside of that… they missed the mark and Sinnoh deserves better.

Generation 5: Black2/White2 are effectively sequels to the base games and honestly the only thing they could do would be to introduce the Fairy Type to the region. Yet if they did, much care should be taken in doing so because Black2/White2 were exceptionally well done, even if it didn't get the rave reviews early on.

Generation 6+: Only region that deserves a new game is Kalos and we all know why. We shall see what Legends Z-A has in store for us, but the rest of the regions are simply too new or have little reason to be updated.

Given above, the only "remaster" that should come should be from Johto(Gen 2) or giving Sinnoh(Gen 4) a Platinum mulligan. Otherwise, their focus should be on a new game with perhaps a Multi-region focus.

like the pokemon arceus game, can survival

i like game pokemon archeus because can survival and that makes it exciting!

Understandable provided that a linear story is still vital. Not too open world when it comes to gameplay.
