Gen 1 is a mess of glitches and terrible type balancing, bad move pools, annoying HMs, and a pretty steep spike to the level curve going from the final gym to the Elite Four. However, I still just love the entire experience so much, especially how open Kanto feels to the player, all of the strangely dark things that never really appeared in the franchise again that are just sprinkled throughout this otherwise really simplistic and childis story, and trying out new weird teams every playthrough (Pikachu, Nidoqueen, Farfetch'd, Hypno, Dewgong, and Ninetales this playthrough, by the way.)

Honestly prefer the weird sprite work from Red and Blue over Yellow's more refined ones, but otherwise a game I really can't find too many things I don't like about it.
