What is "amazingly unlikely" about that though? Revolutionary games that create their own genres (Rogue, Adventure, Dune 2) are amazingly unlikely. Minecraft is just evolution of the games that already existed.
Not sure of the others, but Dune 2 certainly didn't spontaneously big bang in a vacuum either, it was built on earlier iterations of similar games most notable being Herzog Zwei,whose english translation curiously enough is just 2 letters forward on a single letter, it translates as "Duke 2"
that said, played the shit out of dune 2, what a game!
