Deciding on things is hard. Deciding on things together is harder. Dividing chores, deciding on food and movies, voting, managing, - any group decisions.
The core idea behind the Games of Ni comes from classic auction theory and mechanism design, and is backed by research of a large number of Nobel Prize economists thinking on the subject (William Vickrey and Roger Myerson to name just a few).
With Games of Ni you create a game and vote for different options in it. When the game is over, the bot announces the winning option and the compensation to everyone else. Done, decision is taken.
