Minecraft creator Markus ‘Notch’ Persson is worried that Mojang will grow too big and will lose the “indie spirit” the company is known for.

In an interview with Develop, Notch said he would rather the studio to not work on “super polished” games because those require a larger team and a higher budget. He also revealed that Mojang actually has no middle management structure meaning the staff is allowed to work on their chosen projects.

“I hope we can keep the spirit for as long as possible,” said Notch.

Mojang was founded in 2009 with only three employees including Notch. Within a year, the company had 12 employees. In 2011, Sean Parker, Facebook president and Napster founder, offered to invest in the company but was turned down. Mojang currently has 25 employees and as of March 2012 they have accumulated a net income of $80 million.

Mojang CEO Karl Manneh also hopes to keep the ‘indie spirit’ that has made the company into a widely known indie game studio. However, he expects to have more employees in the future depending on which projects the company decides to work on.

“I hope we are still making great innovative games and having a lot of fun,” Manneh said. “We will probably be more people, depending on which projects we choose, but we do everything in our power to keep the ‘indie spirit’ at the studio. Whatever that is.”

The interview with Develop was part of a feature called “Mojang Uncovered” which revealed the innerworkings of the studio.

Notch is currently developing what sounds like a space simulation sandbox game called 0x10c.
