Your Buddies in the Home. Make it Feel Alive
At the home waiting screen I can see that it looks very quiet. People also love to see the people they game with. Auto put in the person's friends into their waiting home screen. Have them randomly mingling around, playing a game in vr or cooking on the BBQ. If the friend is online that person's avatar could be waving "over here" or have a icon that the person is online as well. Then the user can click or interact with the avatar and open a chat with their friend to go gaming.
My quick idea and side note: I do not have a quest yet and am dying to get one. If this idea is something ya like to use, send a quest as a bonus and I can be your tester ;)
