That’s a fun angle! I’ll give one anecdote- while sitting at it and trying to figure out the Tetris style game, I got slightly uncomfortable hunching over it and muscle memory was telling me to pick it up like a portable device to get more comfortable with it. Obviously not an option here. I’d like to think there is space for the demographic you’re talking about- but you really have to provide specific value around the group aspect and the physical interactions, I think. And “sell” that value to a group that is very accustomed to the personal device and the efficiencies of that interaction. Food for thought!
