I really hope the Gen 1 pandering stops completely after Gen 7. Gen 6 had a bunch, but it was alright. Like, wow we get to use the original starters again and they get new special forms! Alright! That was super cool (but why couldn't Venasaur and Blastoise get a second form?) and catching Mewtwo again was pretty awesome, especially with his animation when you get close to it.
Pokemon Go, for now only has the first 150 - legendaries, which is fine because it helped build a bunch of hype for a while and if they tried fitting all 718 Pokemon at once the game would just explode, so they'll do it gradually.
But come on Sun and Moon, please chill with the Gen 1 pandering, I love Gen 1 as much as the next guy. Really awesome Pokemon, cool and mysterious characters, memorable music and just all around great memories, but it's not just the first generation that has this. Every Gen had it's great moments and they should all be appreciated and recognized, especially during the 20th anniversary. Don't get me wrong, they're still doing a great job with the pandering because the new forms are excellent and mostly on rare and underappreciated Pokemon (hell I like the new Meowth a lot more than old Meowth) but give some other gens some love.
