Expansion idea: Giant thrusters on asteroids to build a planet.

[Konebred]

A bit 420 inspired during an early morning gaming session with some old transformers cartoons in the background. Anyways, relatively speaking a hollow asteroid can't be "that" hard to push if you build a rocket engine big enough. Imagine pushing all your asteroids together in one big giant colony flying through space picking up other colonies. Smash all the super hot asteroids together to form a small core, then build up around it. Float through space gathering asteroids like a mini Unicron or Galactus. Build up your own planet and repopulate it with dupes. You would need tons of infrastrcture, maybe some docks or something to connect the asteroids, super resource intensive. I dunno, it might be a bit beyond the scope of the game but it sounds cool in theory.
