Nintendo is looking to make its array of games more social with the availability of GameChat on the Nintendo Switch 2. The feature allows you to video chat with your friends while playing your favourite games. Naturally the streaming feature is ripe for abuse, so as a precaution Nintendo is requiring all users to link their phone number. This should go some way in allaying fears that the app might be misused, though some will not be happy that they have to give provide their phone number to use the GameChat application.
