In 999, “Game Theory” plays a key role and in Virtue’s Last Reward it plays a very central role as it directly affects the fate of the nine. What fascinates you about this idea?


     When it comes to gay theory, I’m an acknowledged expert, but as far as game theory I admit I’m a complete amateur so I can’t elaborate too much. To the best of my knowledge, though, there’s no accidental intervention in game theory, which is—to me—the most charming thing about it.

     With roulette, or dice, or shuffled cards, the outcome is just probability. The fun in this theory comes from the logical prediction of an individual saying, “I think the other person is going to take this type of action so I’ll do this.” But at the same time, humans don’t always make logical and rational decisions, and if everyone aims for their personal gain and makes a rational decision based on that, not only will it cause a disadvantage for the group, it’ll also cause a disadvantage for them personally.

     This title depicts that dilemma, which is what I think is particularly interesting.
     Besides, what does “rationality” mean, anyway?
     You advance through this game by playing the Ambidex Game. You and your opponent have to pick “Ally” or “Betray.” If you both choose ally, you both get two points. If one allies and the other betrays, the one who chose ally will have 2 points deducted. And when your points reach 0, then you will die.

     So let’s say you and your opponent both have 1 point. If your opponent says, “I’ll definitely chose ally!” what would you do? Would you choose ally? Or betray?
     If your opponent really chooses ally and you chose betray, you will essentially cause their death. On the other hand, if the opponent lied and they choose betray while you choose ally, then you will die.

     So I’ll ask once again: Which one will you choose? Will you trust them and choose ally? Or will you not, and choose betray? What would you say is the most “rational” decision?
