No Region Lock on Games
Regardless of where you get your games, you can be sure they'll work on your Nintendo Switch. Nintendo confirmed during its January 12th briefing that it won't pressure game developers to region lock their titles.
This change means that you'll be able to enjoy games that you might not have been able to because they weren't made for your region. This is a huge difference from the experience of importing games on the Nintendo Wii and Nintendo Wii U. These games won't have translations since they will go unmodified for a specific region, though.
