If Nintendo offered N64 games to be purchased for the Switch people would still pay for them in droves. It's weird that they don't offer so much of their past works in any legitimate capacity.
It's genuinely weird that they still don't have a virtual console for anything other than a select few NES games. We're midway through the Switch's lifecyle already!
I've never heard a compelling reason for Nintendo not doing this. Why don't they have a full catalog available on the Switch? It's technically feasible and would make them boatloads of cash.
Probable because of licensing reasons. Nintendo may have a license to distribute a game, but it’s probably limited to the console it was designed for.
