Other Pokémon has gimmicks that would be excellent playable characters in games like Pokkén and Unite but they use the same roster over and over again (Kanto Pokémon + no-Kanto humanoids because they are easier to animate).
Pokémon games are funnier when there's no one Pokémon more important than another and bring us the chance to make new favorites and enjoy Pokémon that we didn't care about before
