I can’t possibly invest 100+ hours in a Pokemon game and lose everything of the battery dies, screen breaks, console is forgotten on a bus or stolen, and so on.
it is nintendo’s choice disable cloud saves on pokémon. splatoon and animal crossing are both made by studios under nintendo’s umbrella, and nintendo already showed they can exert that pressure if they need to with animal crossing.
saying “it’s up to the devs, not nintendo” neither answers the complaint you replied to nor has any semantic relevance to the titles above. moreover, SD cards cannot be used for these titles.
