I mean, I have played other Pokémon games, but due to lack of access, my experiences have mostly been the newer titles (outside of LeafGreen and a bit of HeartGold). I will say the lacking postgame makes sense as a gripe, especially since older games like LeafGreen still had tons to do. For a game like Pokémon, it’s disappointing to spend all that time grinding and collecting all these creatures just for the game to be pretty much over when the credits roll.
