The Switch 1 launch was also a shitshow. Their big launch title was literally a Wii U game and they had the same hodge podge of “what if wii sports but now”. They just had “the nindies” and… yeah.
Considering that Nintendo have actually always genuinely innovated in terms of marketing and more or less set the gold standard for the modern “just communicate direct to consumers”? I increasingly don’t believe that they have this secret vault of finished games that are ready to go whenever. They are just as fucked as everyone else.
