*quietly bathes in salty tears of gen 1 hate*
It's not hate.
It's annoyance at the ignoring of the other generations while Generation 1 continues to get special treatment.
A significant part of Pokemon's target audience probobly wasn't even alive back when Gen 1 came out. In fact, a significant amount of their target audience probobly wasn't even alive when FR/LG came out. And older fans won't suddenly stop playing if Gen 1 dosen't get special treatment. Freaking
PIKACHU wasn't in Gen 5 and did Pokemon bomb then? No. In fact; in Black/White; there wasn't a single pokemon from another generation until postgame. Did the games bomb because they ignored Gen 1? No. Nintendo seems to have got it into their heads that the older fanbase will vanish if they stop worshipping the 151.
Was it though? I really don't remember this much. Seemed to me that most of the popular non-new pokemon got mega evolutions and new spotlights. Eg: ampharos, gardevoir, lucario, etc. The gen 1 starters getting new attention was to be expected considering it was mega evo's first unveiling, and gen 3's starters just got their megas as well. With the new crop of people being reintroduced to pokemon through pokemon go, which only has first gen mons, it seems like a pretty reasonable thing to do.
1: Your first wild pokemon encounter in the game is
forced to be a Pidgey. Not a new pokemon. The first pokemon you can catch in X/Y will
always be a Pidgey.
2: Regional Professor supplies you with; and uses in battle; Kanto starters. He also gives you a Mega Stone for said starters; meaning they'll outshine your Kalos starter. So much for repping your trio Sycamore.
3: Snorlax in the road and Pokeflute quest mandated in the game
4: First Mega Stone you can obtain that isn't plot-mandated? Aerodactyl. Also you can get an Aerodactyl before Gym 2 conveniently.
5: Free Lapras; also Lapras gets a special surf model, and not a minor edit to the blob's shape. An actual model.
6: The legendary birds are in Kalos for absolutely no reason.
7: Mewtwo is in Kalos for absolutely no reason; which means all the Gen 1 legends are in Kalos because... uh... muh Genwun pandering?
8: TWO Mega Charizards! TWO Mega Mewtwos! No other pokemon got this treatment. Meanwhile Gen 5 has to wait until ORAS for a single Mega. [Which gave a lot of love to gen 3 but it's the gen 3 remakes it actually has an excuse]
9: The vast majority of Megas in X/Y were Gen 1.
It honestly felt like in X/Y they were pushing Gen 1 pokemon harder than the actual new Gen 6 pokemon.
You can probobly tell people are a little annoyed now it looks like Gen 7 is going to stuff Gen 1 down our throats and give it special treatment
again what with Alolan Oak who'll probobly outshine the actual regional Professor, and Alolan forms thus far being a purely Gen 1 thing.
We get it. The 151 are cool. But you know what? There are
571+ other pokemon who deserve love as well.
