If it wasn't for Nintendo games many of us wouldn't be considering Nintendo products at all. Often the hardware is weak and with a hugely inflated price and minimal third party support. Nintendo games is the only reason really to consider Nintendo hardware but that's the point. It's a lot of investment in hardware for the few games available. It shows the power of Nintendo games that people still consider buying such hardware.
If every game was multiformat I doubt Nintendo would sell a single console.
I'm considering getting a Switch later in the year and yet only Mario Odyssey interests me.
