Lots of cope in these replies. You can easily look up youtube comparisons of these games to see how similar they are, even mechanically in many cases.

Besides, I agree that Nintendo is behaving badly.
My Switch got a lot of mileage, but you won't catch me dead going up to-bat for Nintendo's overall business strategy. The best thing I can say about them is that they don't kill their own studios like Sony and Microsoft, which really isn't much of a compliment. In the case of Game Freak, maybe killing off a studio would be the right way to embrace the future. After all, PalWorld wouldn't be popular if Nintendo was offering a superior and competitive product in the same segment.
