I would give a testicle for a proper remake, expand the Laguna story, a more populated world, even more battshitery
Pokémon Crystal is just shy of your 25 year threshold depending on what month it was released (it came out in 2000 in Japan), so I’ll say Pokémon Yellow or Pokémon Gold and Silver. We can sit here and nitpick about which is the best, but Red, Blue, Yellow, Gold, Silver, and Crystal were all amazing.
