Would agree. Especially re:Nintendo.

One of my biggest annoyance is when you have multiple switches on a family account. If you use cartridges local co-op (or whatever it is called) requires two copies of the game (a cartridge in each). If you have the downloaded versions/digital download, then any device on the Nintendo account (ie: 2 switches for kids on a family account) can play against each other locally.

I don’t think you can cache/save a cartridge to a device to be able to do their local play feature (ie via ad-hoc connections in a car)
