I liked many of your suggestions, but I did want to single out this part specifically and ask a question: Is it really a bad thing to redo things?
Sure, it might not be best to redo everything all at once, but pretty much all other game series that I can think of make some pretty dramatic changes game in and game out. Pokemon seems to be the only series where the designers seem skittish to change things, which has ultimately influenced the fanbase.
I'm not saying we should embrace a Pokemon future where each game has a different set of Types, certain Pokemon are removed from the game entirely, and combat is always in flux by influences from the combat gimmick of the week. What I am saying is, maybe we should reconsider certain things like Breeding and Egg Moves, Natures/EVs/IVs/, maybe even Pokemon Typings in some cases (Bug/Psychic Butterfree, anyone?).
I love Pokemon, but I can't but look at the series and see an unhealthy amount of bloat. I don't think its enough to ruin the experience by any means, but I do thing some things that are seen as "standard" aren't necessarily the best for the series as a whole. Some others have mentioned things like how breeding and the obscene amount of monotonous time it takes to actually make competitive walls is a huge turn off to many would-be competitive battlers if the system wasn't so unfriendly. Designers are able to figure out solutions to what works and what doesn't by experimenting, and I think this mentality of things that cannot change might be holding back what could be some really phenomenal changes that could make the games even better. They'll never know until they test things out, and they also shouldn't be afraid to revert certain features that didn't pan out.
I quite generally agree with everything you've said on the topic here -- and especially your first part about how just about every other game series does try to change something fundamental about it each main game. Which segways into my next big unpopular opinion...
I love the world of Pokémon, I love the concepts of it, and I love (most) of the Pokémon as well. But the gameplay is archaic and greatly shows its age as time has gone on and the rest of the RPG genre has found interesting ways to change and innovate while Pokémon only tacks on a couple of gimmicks which - while I am actually a fan of in and of themselves - do not and could not solve the fundamental problems with the gameplay.
So,
I want to see Pokémon's base mechanics and systems to be stripped down and get a complete overhaul even greater than the move from Gen 2 to Gen 3.
Once again, I love Pokémon's world and setting and the rest of it. I wouldn't change any of that -- I'm not even suggesting a reboot, and while there are certain Pokémon I would like to just not see ever again, I wouldn't dare remove any of them and at most I'd say a Gen 5 or 3 situation where your initial selection of Pokémon is limited would be as far as that aspect should go.
But I'm sorry, very very little of Pokémon's fundamental gameplay if at all has changed since 1996. Despite all their attempts to improve the pacing and add things on which makes it a little better, Pokémon at its core is hurt by not being brave to change up the mechanics enough to make each game feel truly different.
To illustrate an example, I played through Metroid Prime Trilogy lately. Brilliant set of games, highly recommend if you're into a mix of FPS and exploration and a great sense of progression. But one of the best things about these games is that despite having the same basic premise to its gameplay, there was still
something fundamental at their core that made each different from the other. They didn't just add new power-ups on - though this is also something they did nicely - they completely changed how you played. Metroid Prime 2 introduced a mirror world system - a dark world that's almost a replica of the world you were just travelling through, which just about doubles the amount of world you had to explore and forcing you to figure out which one you had to traverse to progress. This is present throughout the majority of the game and forms the core of its gameplay; ensuring that it's a very different experience from Prime 1 which focused on just having the one world. Metroid Prime 3 introduced both the Hypermode system; wherein you enter a state that drains your health and risks game over for an extremely increased damage output, and the Gunship; allowing you for the first time in the series to not only call in your ship for missile strikes or landing to save at certain points in the game, but also letting you travel between different planets which becomes important later for backtracking for items and using something you find on another planet to help your progress on another.
And you can see this with multiple other franchises, even if you just stay in Nintendo's wheelhouse -- Mario Sunshine is very different to Mario Galaxy is very different to Mario Odyssey; Zelda Twilight Princess is very different to Zelda Skyward Sword is very different to Zelda Breath of the Wild, etc. All of them manage to strike an incredible balance between what people come to expect from these franchises and what is essential about their gameplay, but also introduce some sort of major fundamental mechanics change to make each one feel different. This
is absolutely risky, I won't lie: some of the games I've just mentioned were not well received at all. Mario Sunshine, Metroid Prime 2, Skyward Sword; they're all treated as black sheep within their franchises. But then, you've got Odyssey, you've got Breath of the Wild. Brilliant games that are universally praised and loved and wouldn't have been if they didn't try to change things up. They wouldn't have been beloved if they didn't take risks.
Pokémon does not even attempt to take risks like this. It'll introduce new mechanics, sure; but they don't really change how you play. They just stack on top of the same system you've already had and hence don't really feel that big a difference from the previous game. This leaves us with a series that we can predict to be generally good with each instalment, but they key word is
predict. We know exactly what to expect from each game as they all use the same cookie-cutter formula and only adds things on instead of changing what it is. They're
fun, but they're all the same basic game when you get right down to it -- something that's only an asset for assuring us that transferring our old Pokémon will still be possible, but come on; we've seen them find a way to transfer from Gen 1 to Gen 6. They could handle transferring from Gen 7 to a completely new set of mechanics and a completely new game.
I will admit, there was
one time they changed things up enough about the system -- Pokémon Colosseum. This is the one time they took risks and one of the reasons it's my favourite game. Instead of there being wild Pokémon, there's instead a limited amount you have to steal from other trainers. You've got the Shadow Pokémon system, a system which not only brings a bit of variety to the opponents you fight; which not only gives you an extra challenge on top of raising your Pokémon in general; but
perfectly meshes with the morals of the series. The more you fight by this Pokémon's side, the more affection you give it, the more you spend time with it? The more its heart opens up and the more the shadow guage goes down to return it to normal. It's a great way of strengthening the core of the franchise while also adding in something fundamentally new and unique. And that's not even getting into other points about it; like how the fixed level before depleting the shadow guage means you not only fight a higher level opponent at first, but that before this guage is depleted it's difficult to improve in any way. The Shadow Pokémon system has its flaws, but there were a lot of brilliant things about it that truly shook up the gameplay.
We've had over 20 years of this same system. A milestone the Pokémon company seems to want to celebrate and revere, and mark it by... not changing anything and instead giving out some Legendary Pokémon events for the 50th time. I want to love this series. I
continue to love this series. But more and more I'm finding that I'm just not enjoying the gameplay as much as I used to, but I'm simply putting up with it because I love the new Pokémon. And I do! I love cool new creatures like Decidueye and Mimikyu and Minior. The Alolan Pokémon idea - one which has flaws in execution, but I've ranted enough about that - was also wonderful and prompted me to love these old Pokémon in a new way. And you know what? Maybe
that's what I want. Maybe I've had enough of Pokémon's gameplay and I want to see a new twist on it. Something added to its core which makes it completely different to play. Something that injects new love and ideas for once into something that's been around for 20-odd years. I want Pokémon Gameplay Alolan Form.
I'm not saying anything quite as drastic as, say, changing Pokémon's entire genre from RPG to Platformer or FPS or something. At the end of the day, capturing Pokémon does give a unique spin on the RPG genre and I don't want to see that go away. But that's the
only big spin it's had on the RPG genre and it's been there since the beginning. I need to see it evolve, I need to see it do what other RPGs and franchises have done and just have no hesitation in ripping down the old system and starting from scratch, taking what worked best about the old and re-inventing it with fresh new ideas for new generations. Give us a new game.
