Xbox One parties are not typically invite-only events. In fact, many people who attend Xbox One parties are not even gamers. They are friends or family of friends who have Xbox One consoles and want to join in on the fun. One possible reason why invitations to play Xbox One may not be accepted is because the party is too large or because there are not enough people interested in playing. Another reason could be that the party is too late for someone who wanted to join.
