Cave Game

Cave Game was the first name given to Minecraft, it was meant to be an Infiniminer clone. Not much else is known about it. The only information there is on the project is on Notch's YouTube page. When Notch first started creating the 'cave game', he had planed for it to just be a small project. The title "cave game" was later renamed to "Minecraft: Order of the Stone" (a relation to order of the stick ) and then shortly after, later changed to "Minecraft" as it was much simpler. (blog post)
