minecraft is about building factories too, if you want, with mods like buildcraft and so on.

its rather amazing, you can even eventually end up building star trek level tech where you order items out of a computer that are stored digitally.

if you haven't tried it, check out one of the modpacks like Feed The Beast, or similar, set up a server play with a few friends.

best gaming experience I've ever had.

I programmed an in game robot with LUA to build hedge mazes, and 3d mazes

Cool, might try it out. Factorio is really designed for this so it's much easier to build things than I'd expect in a modded minecraft, but will try it out.
