Quoted from Deaconblooze:My kids have been pushing for a second switch. I've heard account sharing is a bit of a nightmare - any feedback on what I'd be getting into with a mixed digital/physical collection?
Nintendo whale and fanboy reporting in:
Physical games work great, obviously. If you have the paid subscription, it shares saves across systems rather well.
Digital games (I'm 100% digital) share less elegantly. On the base switch where the purchasing account exists, any account can play any game anytime. On other switches, accounts check in online (and require online access to start games) to see what games they have access to. This basically means that only the account purchaser can play digital games on that 2nd switch.
It's not great, IMO. We have a 2nd switch and nobody uses it other than me when I'm on a work trip, and even then I have to carefully manage when/where I start games as it requires internet access. If the kids are at home playing Kart/Party using "my" account, I can't play anything.
