I've been trying to design a game that encourages people to be more social. There is a meme that even when people get together IRL, they end up staring at their own phones. So I've been wondering if a game can be designed to motivate people to gather together, then put down their devices, or at least look at the devices together. (Like forming a larger screen across multiple devices.) I think the game would be location-aware and cooperative. Ideally the game would be a casual game so people could have conversations while playing the game. Either the game mechanics are simple so it doesn't require full concentration/attention, and/or only intermittent playing is allowed/required. (Like the game mechanics require waiting for something to happen.)
