{{main|0x10c}}

Following the end to his involvement with ''Minecraft'', Notch began pre-production of an alternate reality space game set in the distant future in March 2012. 0x10<sup>c</sup> is a hexadecimal number equivalent to 16<sup>12</sup> in decimal, which equals 281,474,976,710,656, which was the number of years that were passed in story since 1988. On April Fools' Day 2012, Mojang launched a satirical website for ''Mars Effect'', citing the lawsuit with Bethesda as an inspiration.<ref>{{citation|url=https://web.archive.org/web/20120402174313/https://www.shadowlocked.com/201203312487/news/minecraft-creator-scores-april-fool-with-project-mars-effect.html|title=Minecraft creator scores April Fool with 'Mars Effect'|website=Shadowlocked|author=Rebecca Fields|date=March 31, 2012}}</ref> However, the gameplay elements remained true and on April 3, 2012, Mojang revealed it as a space sandbox title.<ref>{{citation|url=https://www.forbes.com/sites/alexknapp/2012/04/03/mojang-registers-website-for-its-new-game-0x10c/|title=Mojang Registers Website For Its New Game '0x10c'|website=Forbes|author=Alex Knapp|date=April 3, 2012}}</ref>

The game was eventually put on hold in April of 2013 because Notch had found creative blocks. However, at the time, he was still interested in expanding the development staff to push the game toward release.<ref>{{citation|url=https://www.polygon.com/2013/4/5/4183864/minecraft-scrolls-0x10c-the-past-present-and-future-of-mojang-as-seen|title=Minecraft, Scrolls, 0x10c: The past, present and future of Mojang as seen through Notch's eyes|website=Polygon|author=Brian Crecente|date=April 5, 2013}}</ref> Eventually, the game was indefinitely shelved on August 13, 2013, but Notch added that it could be made in the future if another Mojang employee was interested in developing it.<ref>{{citation|url=https://web.archive.org/web/20130816034249/https://www.geek.com/games/notch-indefintely-shelves-mojangs-space-game-0x10c-1565266/|title=Notch indefintely shelves Mojang’s space game, 0x10c|website=Geek.com|author=James Plafke|date=August 13, 2013}}</ref>

It will involve caffeine and giggling.|September 5, 2011}}</ref> to July 19, 2012, Mojang was co-developing a video game titled ''Brickcraft'' (codenamed ''Project Rex Kwon Do'') alongside {{w|The Lego Group}}. Before the title had reached a significant stage of development, Mojang cancelled the collaboration to focus on developing their own titles (''Minecraft'', ''Scrolls'', and ''0x10<sup>c</sup>'' at the time).<ref>{{tweet|notch|226020149742927873|Remember Project Rex Kwon Do? We cancelled it to focus on Minecraft, Scrolls and eventually 0x10c that we own 100% ourselves instead.|July 19, 2012}}</ref> Despite the cancellation, The Lego Group briefly considered acquiring Mojang, but according to Ronny Scherer, the senior director for the LEGO Games Asia/Pacific division, they decided against it as ''Minecraft'' "was still emerging" and they had "no guarantee that it would end up becoming the cultural phenomenon that it became".<ref>{{Citation|url=https://www.pcgamer.com/the-lego-minecraft-videogame-brickcraft-that-was-greenlit-and-why-it-never-happened/|title=A Lego Minecraft game called 'Brickcraft' was prototyped and greenlit – here's why it never happened|author=Rich Stanton|website=PCGamer|date=December 9, 2020}}</ref>

===== ''RubyDung'' =====
{{main|RubyDung}}<!-- Please add a brief description to RubyDung -->
''RubyDung'', short for "Rubylands Dungeon Game",<ref>{{tweet|notch|1019752622947950592|Dunno if I told anyone this, but that version was called "rubydung", as a placeholder name for a dungeon game in the rubylands rough gameworld i had in my head.|July 18, 2018}}</ref> was a ''Dwarf Fortress''-inspired game being developed by Notch in early 2009. The game would have focused on being easier to play and more accessible than its predecessor, and would have featured both isometric and first-person viewing modes. Upon discovering ''[[Infiniminer]]'', Notch decided a first-person block-based game would be a better choice for the kind of gameplay he had in mind,<ref>https://web.archive.org/web/20210513102920/https://notch.tumblr.com/post/227922045/the-origins-of-minecraft#_=_</ref> and code and art from ''RubyDung'' was reused to create ''Minecraft''.

===== ''Zombie Town'' =====
{{main|Zombie Town}}
''Zombie Town'' was a ''GTA: Chinatown Wars''-inspired game being developed by Notch in early 2009. It would have been a zombie game based on one of Notch’s earlier projects, ''Left 4k Dead''. The game was never completed, but Notch later reused its character models and textures for the player character in ''Minecraft''.
