"first main series Gen 10 Pokémon game(s)" = first games where there is fan consensus that this is the main series game following in the tradition of Red&Blue, Gold&Silver, ... Scarlet & Violet. If it's not obvious whether a game is or is not this game then a poll will be set up asking "Is/Are Game(s) the first main series Gen 10 Pokémon games". Wording is to exclude weirdo games like Let's Go Pikachu and Eevee or Pokémon Legends Arceus which are sort of main series but not.
Update 2025-02-03 (PST) (AI summary of creator comment): Pokémon Legends Z-A Clarification
Exclusion of PLZA: Pokémon Legends Z-A is not considered a main series Gen 10 game at the time of this market.
Future Considerations: For PLZA to be deemed as part of the main series, it would need to show significant changes (for example, incorporating systems like VGC into PLZA or presenting as paired games).
1,000@Kronopath Right now, definitely not. Based on rumours it sounds like the Gen 10 "main series" games are in development and are not the same thing as PLZA.
Things would have to appear significantly different for me to think PLZA was the main series game. Something along the scale of moving VGC to PLZA, or splitting it into two paired games.
