Yeah because they don’t want their IP’s getting taken away the same way. They’re actually so crazy about it, at one point they actually launched an ad campaign telling people not to call other game consoles from other companies “Nintendos” because of that issue. That’s partially why they’ll investigate other games that are like theirs incase they use similar assets or code. They went after Palworld recently because they’re developing a new game and don’t want Palworld to be too similar to their game, and thus, losing part of the Pokémon IP.
