Is the implication that they won't be able to write an in-house emulator? So did they wait for someone to port an SNES emulator to Switch before they can put those old games on their online service?
It's a weird assumption. Like I said, emulation for backward compatibility is common. Do they always just wait for some random strangers to implement an emulator for them?
Do you really find no difference in buying games (or the license to play them) and subscription services?
