Funny thing is, 3rd party games on the Switch have the ability to invite people or friends to your game session or lobby, but not most of the 1st party games, though Nintendo is slowly starting to incorporate it, but such modernization with online takes them ages. lol
I didn't know....I just remember my friend trying to play a Nintendo game...and using this complicated system of communicating....he was annoyed.
While....Xbox and PS (I believe)...I send an invite to a party and we are talking 30 seconds later.
Though...it would be nice if games added your party friends to their internal friends list (or squads....of whatever stupid name the game has)..but I guess a party can hold up to 12 peeps...and most games are 4 only.
