# Good Decisions, Good Outcomes

We have discussed repeatedly over the past year that fun games let you make meaningful decisions. David Henderson comments on a recent football game and the distinction between decisions and outcomes.

Usually, the best choice is the one with the highest expected value (probability of outcome times value of outcome). People frequently look at solely the outcome and then attribute it to the decision, whether or not the outcome was a likely result of that decision. Winning the lottery is a good outcome for you, but playing the lottery is almost never a good decision because the cost of a ticket is more than (odds of winning) times (value from winning); depending on how you estimate taxes, inflation, and the chance of splitting the prize, the Powerball even-odds point is around \$1 billion.

I have mixed feelings about games where you make good decisions and lose. This is not the case of single-player games scripted to be perverse, where what looks like the right choice is a trap or all choices are traps. I am thinking of multiplayer games that are anything less than 100% strategy with all information known in advance. We want some unknowns, and making decisions in the face of unknowns means occasionally things come down against you. When the odds are 50-50 and you lose a coin flip, yeah, that happens all the time. When you win unless you lose 5 coin flips in a row, that still happens 3% of the time. I like to think of myself as comfortable with probability and true randomness, but having a 97% chance to win and still losing through no fault of your own is really frustrating. It is absolutely necessary that players lose 3% of 97% chances, but it is still really frustrating.

It is frustrating on another level when people celebrate those 3%s as great victories, rather than blind luck. Don’t get me wrong, if you are in a position where your only chance to win is five coin flips in a row and playing conservatively guarantees a safe loss, take that chance. High variance solutions can be your friend, and even if you lose that game (as you most likely will), it was the right decision. But if you started with equal odds and fell into a situation where you needed five-in-a-row to win, you probably made some bad decisions along the way. And if you are that guy who immediately set up a five-in-a-row situation to win immediately or quit immediately, you are what is wrong with online gaming.

Celebrate your victories, but also celebrate good decisions, whether or not they lead to victory in that particular case.
