Okay /vp/, suppose you're given an offer by Gamefreak. You may make one generation of your choice non-canon. This includes everything that was introduced; region, Pokémon, people, and mechanics that were introduced in it. None of which will not appear in any game in the future and are removed from any games that came out after the generation you removed.
HARD MODE: No Gen VI, though of course this is optional
