If Zelda is so great why doesn’t Nintendo make it available on more platforms? Being able to run Nintendo games is a prime feature of the Switch product, and being able to run Apple software and services is a prime feature of an iPhone product. By your definition anything useful about an item is simply a marketing tool?

It’d be a very different world if nothing was allowed to have unique access to anything. It might even be better, but it would be a long way from this current version of capitalism.
