Something rare happened in MWO of all places a while ago. There was an opportunity to not only make a change in direction, but the choice had predictable consequences. MWO wanted to update its Matchmaker to give its players a better match experience, and opened up to the community for proposals. Unlike adding new features which may or may not be well received, making matches is a math problem, and math problems can be solved.
So that is what I did. I took the Matchmaker solution that PGI selected, alongside my own proposal at the time, and crunched the numbers to see what the results will be months later. I then posted these results for all to see, 9 months ago, before the update even happened.
The predictions were as below. The most easy metric to compare against is the sum of the 3 center bars.
We haven't quite reached 480 average games in the last predicted graph because the increase in pop from COVID slowed down the progression of average games (though an increase in pop is always a good thing), but here are the results up to the end of the March 2021 season:
So the predictions and actual results are close, so what?
Well it turns out that how happy players are, and their willingness to keep playing the game (their retention rate) tracks closely with their WLR.
People close to 1 WLR represented by the green line are consistently the happiest season to season. Players that get further away from 1 WLR in both directions are less happy. This seems to indicate that new players are being given games which are too difficult for them, and they leave, and veteran players are given games which are too easy for them, and they leave as well.
Our goal is increasing player happiness, which means better retention and a larger player base. As reference, we can see the impacts of past decisions in the retention graph.
In (A) we see the baseline retention rate when mech packs were still released monthly. In (B ) we see what happened when MWO was announced to be on maintenance mode with no new development. In (C) we have Daeron being hired, and MWO coming off maintenance mode with new balance and content updates promised and delivered.
The impact of business directions (A), (B ), and (C) is clear. At the same time, player happiness is still consistently being affected by the Matchmaker. If we wanted to improve retention rates and grow MWO's player population further, wouldn't we want to increase the proportion of the player base in the green 1 WLR ratio line? Currently as of the last season 28% of the population is in the green line, if we can boost it to 100%, then this action can boost the average retention rate from (C) to (D), an even bigger improvement than from (B ) to (C).
But is boosting the retention rate to (D) even possible? Coming back full circle to the start of this post, the Matchmaker is just math and the results of math is predictable. The distribution of WLR from the current Matchmaker was accurately predicted 9 months ago. The Matchmaker I proposed then would have put 75% of the population into the green line. With more work, a Matchmaker that does so with 90-95% of the population can be created.
Lastly, how big an impact are we talking about here? A "dumb" way to do it is to look at steam charts (https://steamcharts.com/app/342200), and add 10% to the monthly change every month. -10% becomes 0%, 0% become +10%, +10% becomes +20% etc. There is a better way to calculate this of course, but I think this post has become long enough, don't you?
