In a recent report by Swedish site IT24, they stated that Mojang's 2012 earnings were at about 1.5 billion kronor (about $238 million) and that creator Markus "Notch" Persson pulled in a hefty $101.4 million dollars. Notch had a few comments on Reddit about it all.
Notch stated that while he grew up in a relatively poor family, once he found a decent job he didn't have to worry so much about money for eating out and other everyday expenses, but still had to save up for going trips or to be able to buy new computers or consoles. Things have changed for Mr. Persson with the runaway success of Minecraft, but he still remains a down to earth person through it all.
Now, all of the sudden, as a result of how modern society works, I managed to somehow earn a shit-ton of money. I still like playing games and programming, and once I had the latest computer and consoles, there really isn't much more to spend the money on than traveling. I might eventually get a driver's license so I can buy a car.
I think the right way to use money like this is to set a decent portion aside to make sure my family is comfortable, spend some on living out your dreams, and then try to put the rest towards making society a better place. For me, this includes charities that help children, and charities that help promote freedoms I think are vital in the coming dozens of years, such as the EFF.
His response was that they do not for ownership and licensing reasons, but also added;
Instead, we focus on trying to be as fair and permissive with our employees as we can. If people agree to work for us, we'll pay them, but we won't claim to own them. People can make games in their spare time, they can somewhat flexibly move between projects as they wish (right now the web team is understaffed, though...), and we try to have the most fun we can have.
If someone or several people at Mojang makes an awesome game in their spare time and quits to work on that, I would honestly be happy for them. That's how Minecraft got started, and I will never let Mojang be a place where we want to own people.
It sounds like Mojang would be a fun company to work for. I may have to freshen up my resumè as it doesn't sound like the weather in Sweden is any worse than here in Wisconsin.
