What? Surely seeing something popping up on steam and buying it happens far more than someone spontaneously buying a game in a store when walking around town/ a mall.
Maybe I’m a recluse, but I can’t remember last time I went into a store that stocks a meaningful amount of games other than second hand shops. Are physical games really that large of a margin anymore?
I’m not sure I understand what you are saying. What part of the OS should managed the packages? The creators aka. Microsoft/Linux foundation/Apple/Google, the distributor, or a kernel module? What about cross platform package managers like Nuget, gradle, npm?
