You can think of one instance as a wapper around a single game server.
With that friend/family 10 instances limitation, those would be any game server where you’re making a game server just for your friend, and not yourself and your friend.
So out of those 50, you can only have 10 f/f instances, then another 40 for general use if that makes sense. Or just have all 50 for your own use.
