Nintendo's virtual game card system takes a little time to set up, but after that, sharing digital games between Switch consoles should be a breeze... at least under certain conditions.
The upcoming Switch 2 launch title Mario Kart World was developed for the original Switch, before the team realized the hardware couldn't handle it. This is thanks to a new developer interview from Nintendo.
If you were hoping to avoid the chaos that has accompanied the Switch 2 launch by pre-ordering directly from Nintendo, that may not make it arrive any faster.
