I have a game where players will play 2x2 decision matrix games. (Prisoner's Dilemma, Battle of the Sexes, Stag Hunt, etc). There are two players, a primary player (blue, on the horizontal part of the matrix) and a secondary player (red, on the vertical part of the matrix). Both players can make a binary decision. There are 4 potential payoffs depending on the combinations of the two players decisions. Unlike academic examples, the payoffs in this game are not symmetrical or mirrored. Each payoff value is a random number between -100 and 100. The payoff affects the players score.
This is the core gameplay mechanic so I need it to be intuitive and enjoyable. I've been play testing it myself and I immediately feel that the information is hard to take in.
Right now I have this very basic approach:
So in this case, if the primary (blue) player takes action and the secondary (red) player does nothing, the primary player will lose 10 points and the secondary player will gain 40 points.
How can I improve this interface to maximize ease of use?
