Aside from the cloud saves.
There are some hoops to jump through to have games on multiple Switch consoles, but Nintendo is aiming for a more elegant solution.
In an interview with CNET, Doug Bowser was asked about the portability of games for the system, specifically about taking a game on the road.
"I could see myself wanting to take the smaller Switch on trips while leaving the household Switch behind. But then, how would I transfer games between systems? Nintendo hasn't made it easy to do that, but there might be a solution coming. "Yes, you will have the ability to transfer between devices, your gameplay experiences. More to come on there, but that is the intention," Bowser told me.
Currently, it is possible to sign into Nintendo accounts on multiple Switches and redownload games, and accounts with Nintendo Switch Online subscriptions can use cloud saves to move most games over to a second system.
