Earlier today (February 7), Minecraft creator tweeted Double Fine's Tim Schafer with the offer: "Let's make Psychonauts 2 happen."
He later told Rock Paper Shotgun that he was "serious" about the offer.
It follows comments made by Schafer to Digital Spy that he would "love" to make the game but lacked the funds to create it.
"I mean I get a lot of, on Twitter or whatever, daily questions about Psychonauts 2. And I would love to do Psychonauts 2, I've actually pitched that to publishers several times and no-one has taken the bait so far," he said.
"So it is hard because fans often don't know how the business works, with the difference between a developer and a publisher, it's hard to explain that."
Psychonauts is a platformer featuring a psychic boy who can explore the minds and memories of others. It was critically-acclaimed upon release in 2005.
The game was released on Mac last year, while the PC version was updated with Achievements and cloud save support through Steam.
