Resolves YES if, before January 1st 2031, a mainline Pokémon game is released that effectively brings back the “National Dex” in the sense used in gens 1–7:

• The game’s data must include every previously released Pokémon species (at least one fully functional form of each species), up to that generation’s roster at the time of release.

• They do not all need to be obtainable in normal gameplay (they may be transfer-only, event-only, etc.).

• It’s enough that all required data for them to function exists in the game (models/sprites, animations, stats, moves, abilities, etc.), so that they can be used in battles if made available.

• A literal “National Dex” UI entry or Pokédex number list is not required.

What does NOT count:

• Spin-offs, mobile-only titles, remakes that still omit some species’ data, or games where some earlier species simply don’t exist in the code at all.

• Future patches after 2030 that finally add “the last missing” Pokémon do not make this YES unless the final “all Pokémon exist in the code” state is reached before 2031-01-01.

I will resolve based on official releases, credible datamines, and community consensus. If it’s still unclear by 2031-01-01, I’ll wait for clarification but aim to resolve according to the spirit of “all past Pokémon are at least coded into a mainline game again.”
