Speaking to a livestream earlier this week, Persson told listeners he had no future plans for 0x10c and would focus on making smaller-scale games. Persson, according to Geek.com, said he'd have no problems with another Mojang developer picking up where he left off.
But now it seems a group of enthusiasts from the 0x10c subreddit will be taking up the mantle, although what they build would appear to share only this game's name. Speaking to USGamer, the project's lead and head writer said the group wouldn't use "any of [Persson's] old code, his name or anything."
They'd essentially be building the game from scratch. What Persson did show and describe of the game was an 80-second gameplay trailer back in October (followed by a test of 0x10c's multiplayer) and a big-picture view that the game would "feel a bit like Firefly," the one-season science fiction series with a cult following. If the community team is not using any of his code and doesn't have much to go on in the way of a story or feature set, it'll more or less be their own game, just using 0x10c's name.
[Correction: The community appears to have been aware it cannot use the 0x10c name (it is a Mojang trademark) and are calling it "Project Trillek," which is a phoneticization of 0x10c. A previous version of this story had said this community game would use 0x10c.]
Kotaku emailed Persson for his thoughts on this but didn't receive a reply by publication time.
