Marcus "Notch" Persson has created a mini-empire out of Minecraft, using its success to create a bustling studio juggling multiple projects. But he isn't expecting to turn out gold constantly, and thinks that the studio's smash hit will probably be the exception rather than the rule.
"If people are expecting [another game as popular as Minecraft], they will be disappointed," Persson said in a Reddit thread (via Beefjack). "Minecraft is a one in a million fluke." Persson will be able to prove if he's right with the upcoming releases of Cobalt and Scrolls.
He also said he's hands-off with Minecraft now (except "broad strategy decisions"), and so he has "no idea" what the future holds for the game now. "Sales keep going up all the time, and there's an infinite amount of stuff we can do," he said. "Hopefully modding will become easier soon, too."
