Imagine how many they would sell if it ran on something else besides a switch. I'm not paying $500 just so I can play the three switch games I'm interested in.
They make awesome games solely to sell systems.
I could be wrong too, but I don’t think most of their money comes from their own games.
Actually, thinking about their other franchises like Pokémon, Animal Crossing, Smash, etc. you’re probably right, but I still fell like the way they act/view themselves is in-line with my comment.
