They don't actually need to make an achievement/trophy system. Just allow others to create one.
I don't need a trophy for jumping on 100 goombas. But if a game already has it on the PC, XB, and PS - then allow it on the Nintendo.
Well, multiplats with achievements have them on Switch too. Disgaea 5 for instance. What people often want are systemwide achievements, notz ones that are only available in the game in question.
