In Facebook Horizon, have a store where you could purchase a copy of a licensed game(Monopoly, Risk, etc.). Then when you enter a party, as long as somebody has a copy of a licensed game, the group can play it. I could go to the store to purchase a board game, then my friends could come over and play it with me or I could bring it over to their house. It should be the same with Facebook Horizon, as this could be the first major VR social platform, with a company behind it with the resources to get large companies to sign on board and sell their products. This would massively increase the popularity of Horizon, because board games are very popular so a lot of people would come to the platform.
