0x10c

0x10c (pronounced "ten to the c") is an unfinished sandbox science fiction video game previously under development by Mojang AB. It was announced on April 3, 2012, by Markus Persson, the game's lead designer. The game was indefinitely postponed because Persson found himself burned out and demotivated after so much early effort were spent into planning and designing the game, up until the point that it "sucked out any fun from the project". Persson then stated he will instead most likely continue to work on smaller projects for the rest of his life, rekindling the reason he loves programming games in the first place. The game was later cancelled.

The announced features included a fully working virtual computer, random encounters, an advanced economy system, and also single and multiplayer modes in a consistent universe, or "Multiverse". The game takes place in the year AD 281,474,976,712,644 (around 281.5 trillion years into the future) after people start waking up from "deep sleep" caused by a bug in deep sleep cells that were released in 1988. is a prefix in many high-level languages used to indicate a hexadecimal literal. 10C in hexadecimal is equivalent to 1612 in decimal, which equals 281,474,976,710,656, the number of years passed in the story since 1988.
