I have a new potentially unpopular opinion.
In X/Y, the fan pandering to Kanto/Gen 1 wasn't
that bad. Yes, it was there, and it was a problem. But to be honest, it never bothered me that much when I played these games. I have complained about it in the past, but looking back now, I regret doing that. It did not bother me as much as I have said at previous points. I blame the fandom for making me think it was a bigger problem than it actually is. Sometimes, the Pokemon fandom is too much of a hivemind, it can be easy to get absorbed into opinions that are popular to have and it may seem like you have opinions you might actually not have (so in a way, I'm really glad that this thread exists since it is a good way to differentiate yourself from the rest of the fandom). Anyway, the fan pandering in X/Y might have bothered others to a large degree, but it didn't bother me that much.
I want to take a look at some common complaints regarding this and see how I feel about them.
- Santalune Forest having the exact same layout as Viridian Forest. I never even noticed this when I played through X/Y, I only learned it later on through people posting about it on the internet. I don't really have a problem with this. If anything, my only real complaints about Santalune Forest are that it felt too small and lacked optional areas compared to Pinwheel and Eterna Forest.
- X/Y had many Mega Evolutions from Kanto. That's true, but there were many from Hoenn too. Johto and Sinnoh also got a few as well. So that's fine. I also like when Kanto Megas are successful. If they can take a boring old Kanto Pokemon and spice it up to make it interesting again, I'm all for it.
- Getting a Kanto starter early in the game. I didn't mind this. You have to obtain it, but nothing forces you to use it. I just boxed it after obtaining it and went with the Pokemon I wanted to use instead, then I later evolved it for Pokedex purposes during the post-game.
- Snorlax blocking the way and has to be awoken with the Poke Flute. This is the kind of reference I'm actually okay with, and it makes a lot of sense. My only issue here is that this is the only way to get a Snorlax in the games, and you only get one chance.
- Apart from the Kalos legends, there are only Kanto legendaries in the games. Not much of a problem for me, because there are barely any Kalos legends to start with. And the way they set it up means that no matter how you play, you'll always get 2 legends from both Kanto and Kalos. While you are forced to encounter the legendary bird once after beating the game, you have to actively hunt it down to get it, and the odds of randomly running into it are quite low. You also have to actively go and look for Mewtwo if you want it.
- Some moves like Psychic and Hyper Beam uses the original sound effect from Gen 1. I found it a bit weird but I didn't really mind it, and I stopped noticing after a while since I always turn off animations eventually.
- The first wild Pokemon you'll encounter in Route 2 is predetermined to always be a Pidgey. I didn't mind, I just caught it like I would have with any Pokemon I didn't have yet. Once you are past it, there are several other Pokemon you can get here. Not all of them are from Kanto, and Pidgey is not among the most common ones. Also, completely unrelated, but I just learned this from Bulbapedia: wild Pokemon cannot break out of Poke Balls thrown at them on Route 2 in X/Y. I didn't know that! It makes Kalos Route 2 the perfect place for catching fodder Pokemon. Wish I had known about that earlier...
- There are many Kanto Pokemon in X/Y overall. That's true. But there are many Pokemon from the other regions/generations as well. I didn't notice the large number of Kanto Pokemon in the games until I looked at the
Serebii page for unavailable Pokemon in the games. It shows that in total, if we include the post-game fossils and Friend Safari, only 8 Kanto Pokemon are missing from X/Y (Mew included). There are considerably more Pokemon missing from other regions but I wasn't too bothered by it since X/Y has a very large amount of obtainable Pokemon on the whole.
To summarize, while there was quite a bit of fan pandering to Kanto/Gen 1 in X/Y, it didn't bother me that much. And it could have been much worse. Plus, there was a lot of references to the other regions and generations as well, and while Kanto/Gen 1 might have gotten the most references, I didn't really mind. I have been unfairly harsh towards X/Y for this in the past, and that is something I regret, because it wasn't that bad. And I think this is somewhat unpopular because it seems like X/Y gets a lot of hate for their fan pandering, but I don't think it is that bad.
So that's that. Now for the next part. I'm not sure if this part is unpopular but I want to continue with it anyway.
When it comes to fan pandering to Kanto/Gen 1... I think S/M are
a lot worse than X/Y. There are so many Kanto Pokemon in the games, especially early on, while not nearly as many from the other regions (the Dex expansion in US/UM somewhat helped with this though, especially during the early parts of the games). S/M has a smaller Pokedex than X/Y and their Pokemon variation/distribution isn't as good, several Kanto Pokemon such as the Rattata, Zubat, Magikarp and Diglett lines are way too common. Alola forms are strictly Kanto Pokemon only, compared to Megas which at least represented most/all regions. When it comes to exclusive Z-moves, the only Pokemon to get them that aren't from Alola are all from Kanto. Then there are so many references to Kanto during the main story, as well as other minor things that annoy me such as the recreation of the Nugget Bridge and the "Kantonian" Gym in US/UM. And other things like Diglett's Tunnel (this is what we get after the great caves of Kalos?). However, I am not that bothered by Red and Blue being the bosses of the Battle Tree, that is something I am fine with. The reason is that you do statistically not get to battle them as much as the other special trainers if you battle at the Tree a lot. In total, I feel like S/M had too much fan pandering and focus on Kanto and Gen 1 while they didn't have anywhere near as much focus on the other regions, the references to Kanto more or less completely overshadowed all the other regions.
S/M were also released after we had seen a lot of fan pandering already, with things like X/Y (but again, it wasn't that bad), Pokemon Origins (which I admittedly never watched) and Pokemon Go (which I have admittedly barely played). So it might seem weird to say this since I wasn't that affected by the previous fan pandering, but that is how I feel. When I wanted Game Freak to focus on the new Pokemon, the new region and then new features in S/M, they decided to do the complete opposite and focus on the oldest possible in way too many instances. It was a lot more annoying for me in S/M than in X/Y. US/UM was a little better, mainly thanks to the Dex expansion, but otherwise not that much.
That said, it could still have been much worse. Island Scan did for once not have a ton of Kanto Pokemon, it felt more focused on other regions instead. In S/M, it had the Johto and Unova starters rather than the Kanto starters. In US/UM, it does have the Kanto starters, but it also has the Hoenn, Sinnoh and Kalos starters. Out of all the non-legendary Pokemon you can meet at Ultra Wormholes, none of them are from Kanto (or Alola), all of them are from Gen 2-6. Regarding the Fossils, they chose to include Aerodactyl and the Sinnoh/Unova Fossils in S/M, not Kabuto/Omanyte. US/UM added them, but they added the Hoenn and Kalos fossils as well. So while it was bad in Gen 7, it could still have been a lot worse.
I guess that's my unpopular opinion. I thought about this after seeing X/Y getting a lot of criticism for their fan pandering, but I disagree. It wasn't that bad. To me, it was considerably worse in S/M and US/UM, and I think they deserve more criticism for it.
