Super Mario and the 80/20 Principle

Italian economist Vilfredo Pareto noted the 80/20 connection while at the University of Lausanne in 1896, and published his findings in his first work, Cours d’économie politique.

Pareto showed that approximately 80% of the land in Italy was owned by 20% of the population.

But this phenomena doesn’t stop there.


Did you know?

  • 80% of the cars on our roads occupy about 20% of the roads
  • 20% of the words in the English language, occupy about 80% of the pages in our books.
  • 20% of an organization’s customers contribute to 80% of the revenues
  • 20% of the people in the world own about 80% of the land
  • 20% of software bugs are responsible for 80% of the debugging
  • 20% of insurance customers are responsible for 80% of the claims
  • 20% of the Fortune 500 accounts for 80% of the total market cap of the index.

This universal law of nature shows up everywhere.

If you multiple 80/20 by 80/20 (that is, 80% x 80% and 20% x 20%), you find that the law can be broken down to 64/4, 50/1, or even 40/0.2.

That means that about 4% of an organization’s customers might be responsible for 64% of the revenues.


80/20 in Video-Games

I decided to test this theory by applying it to the delightful example of video-games, inspired by a recent conversation with Blake Harris, author of Console Wars: Sega, Nintendo, and the Battle That Defined a Generation.

Nowadays, walk onto any form of public transport and you’ll be hard-pressed not to find people of almost any demographic playing mobile games. The convergence of cloud, mobile and social has resulted in a 10X increase in the number of gamers in the world, which today stands at more than 2.3 billion, while 45% of US gamers are now women, thanks in no small part to mobile gaming.

It’s not hard to find examples of the Pareto Principle at work when it comes to mobile gaming.

Adweek found that 70 percent of in-app purchase revenue comes from just 10% of in-app purchasers (also known as ‘whales’), who also account for 59% of total revenue.

The top 30 Sony Playstation games of all time sold a combined 115 million units.

The top 20% (or six games) of this cohort, accounts for 66m units, or 60% of total units. The list was topped by Unchartered 4, Spider-Man, and The Last of Us.

The top ten PS games of all time

The top 63 Xbox360 games of all time sold a combined 225 million units.

The top 20% (or twelve games), sold 131 million units, or 59% of total units. The list was topped by Kinect Adventures, Grant Theft Auto V and Halo 3.

The top ten X360 games of all time

And finally, an old childhood favorite of mine, the Nintendo Entertainment System.

The top 75 ‘NES’ games of all-time sold a combined 236 million units.

In this case, the top 20% sold 141 million units. Again, about 60% of sales.

Unsurprisingly, the list was topped by Super Mario Bros, which alone accounted for almost 20% of the cohort’s sales, Duck Hunt, and Super Mario Bros 2 and 3.

The top 20 NES games of all time

The results are more 60/20, than 80/20, perhaps because we’re taking a sample of the highest-selling games of all time and ignoring the long tail-end of also-rans and bombs. What’s striking though, is that in all of these cases, the top 20% of these consoles’ bestselling games account for about 60% of sales in the cohort.


Lessons Learned

What this tells us is that, whatever your focus — videogames, sales channels, marketing strategies, customer segments, product features, employee hires, and so on — the universe will almost mandate that the top 20% will deliver the lion’s share of the value (or on the flipside, the lion’s share of the pain, as is the case with difficult customers or employees who you might be well advised to let go).

In order to get the absolute most out of your time, money, and improve your performance many times over, identify and amplify your 20%, while eliminating or spending proportionately less time and money on the 80%.

Don’t build a 100-button remote control, when a 4-button remote will do.
