Minecraft creator Markus “Notch” Persson has again explained why his game isn’t on Steam, despite Valve having made several changes that address some of his concerns regarding the platform.

A year ago, Notch stated that Minecraft wasn’t on Steam because “openess is awesome” – because his company wouldn’t be able to “sell capes or have a map market place on minecraft.net that works with Steam customers in a way that keeps Valve happy”.

Since then changes to Steam appear to have nixed these concerns, but Persson was still reluctant to see Minecraft on the service.

“Yeah, it seems like pretty much all the things we wanted to do are possible on Steam now, which is brilliant!” he began.

“Since I made that blog post, Minecraft has kept growing very fast (and it selling faster than ever), which combined with us not being on Steam leads to some potentially interesting strategic positions. I’m not quite sure what those are, but we’re a bit wary to submit Minecraft to Steam without knowing more about what we want to do.”

The potential for a Steam to become something resembling a monopoly appeared to be at the forefront of his mind.

“As much as I love Steam, I do somewhat worry about the PC as a gaming platform becoming owned by a single entity that takes 30% of all PC games sold. I’m hoping for a future where more games can self-publish and use social media and friends to market their games,” he said.

“Perhaps there’s something we could do to help out there? I don’t know. If nothing else, we might work as an inspiration for people to self-publish.”

Mojang would remain independent for now, even though that meant the cancellation of a recent unannounced collaboration, said Persson.
