Yeah, you're right. I'm aware. I'm just saying that even if it was contracted out to a different studio, anything "Pokémon" should count the same as their "first party" rule when it comes to game keycards.
I'd expect the same if they outsourced a Zelda game like with Cadence of Hyrule
Edit; I think I came across as unclear and as if I avoided the point. Sorry. The original post is correct, as are you for pointing it out. I don't disagree with either of you. I disagree with Nintendo. It shouldn't just be first party games. It should also be Nintendo exclusives or at least Nintendo IP, I think.
Ideally no games are key cards, but if they MUST BE, then I don't think it'd be unreasonable to cast a slightly wider net than strictly first party. Pokopia could easily have been included
