I think there was probably more evidence in favour of minecraft being a success. For example widespread popularity of lego and other various sandbox games.
Minecraft is also relatively simple to understand, pick up and place blocks. I assume that 0x10c will have a much steeper learning curve.
Though it was certainly a long shot that minecraft would be as popular as it is today, the question is whether lightning can strike twice?
I'm sure that 0x10c will still a profitable game but I doubt it will have sales numbers that approach minecraft's.
