Make no mistake. First, they react to folks who weren't happy with Gen V for being pretty inventive and fun (B2W2 being the most jam-packed Pokemon games to date, and dream radar made them doubly fun) by stuffing kanto refs into XY when they don't have any context to speak of, but folks dismissed it because of fun stuff like the amie minigames and Megas even though the post-game was laughably short and the battle maison cheats like hell, but it also had great online to make up for it.
Then, ORAS invades and after everyone gets hyped for finally getting Hoenn remakes that could easily surpass HGSS in quality and with the Gen VI Online engine could be the best games in existence, they absolutely ruin it in every possible way to the sake of pandering to an audience who wouldn't care to play those games to begin with, by dumbing down the entire difficulty of the game, adding hand holding, dumbing down contests to the extreme by removing the skill-based multiplayer minigame and removing the sheen limit (thus making your pokemon insta-win based on the appeal round if you max out their stats with rainbow blocks), followed by a move that felt like a stab in the heart with the removal of the battle frontier and Tower with a lazy reskin of the Maison from XY that didn't even change Ace Trainers and Lasses to the ORAS versions because they were that lazy, along with not changing the rosters of the Maison letters to at least be different, which followed by their insulting explanations of only doing so because they assumed kids today with their mobile games are too stupid to accept a challenging game nowadays even though I played through Gen III during the hardest times of my childhood and the only thing that made me bonkers were the braile puzzles, (that were one of the FEW THINGS they kept hard and made even harder for some reason) but somehow the fanbase did not do the right move of rebelling against Game Freak and instead excused it due to the few cool things they did add like more megas, cool Secret Bases and removing an HM
A year goes by, the fanbase explodes because they decide to take a gap year, instead announcing Pokemon Super Mystery Dungeon, which came off the heels of a pretty average predecessor itself, only to be the best Pokemon game on the 3DS and at least the one with the best story (even for non MD fans), only to be shafted by the main series fans due to being niche, and they return with SM after some RBY VC releases and the megahit of Pokemon Go that actually was a fun successor to the Pokewalker in some way. They actually undo a lot of the tragedies ORAS did and expanded on the removal of the Fly HM more with pokeride and bring back a fun challenging experience with a decent post-game and a fantastic post-game facility, but removed the national dex for no real reason and made a bank dex that can't even reset with every new game you sync up to it, and people excuse it because well, the games are actually good (barring the long story which bugged some people, and kanto shilling with Alolan forms and special Z-moves)
USUM came after that, and they were filler games that were just lazy DLC addons to SM but somehow made it worse to play due to the story being slow and not skippable, (despite this being made a year after the originals) and the national dex STILL remains removed while they also failed to fix the other minor problems SM had and made it worse thanks to a new dev team, but people again excused it due to the guise that third versions are usually lazy. (even though BW2 broke that trend ages ago)
And now we have this, a game that once again fixes things from the old games by reintroducing Pokemon following you, gorgeous graphics and the best looking game in the franchise, only for it to remove wild pokemon battles, pander to the people who cause this dark age to begin with with only 151 mons, (when there's no excuse to at least allow the other mons you can get in GO up to Gen III/IV) no indication that the short length of Kanto is gonna get addressed for a SIXTY DOLLAR GAME, and the removal of online.
Mark my words, if this does well, Gen VIII will somehow suffer as a result. It may start with something small like the removal of TMs or Berries, or with the continued removal of the national dex/post-game facilities/online hubs. This cannot be tolerated and I legit fear that GF will shoot themselves in the foot by making the franchise more and more casual by removing features that have no reason to be removed at all. This didn't have to be a mega hardcore game, but this could at least be one worth the pricetag and engaging to ALL instead of a tiny subset. Even GO I feel did things better considering the context of the game itself.
