Colony ships, for sale cheap!

[Quikngruvn]

This has been bugging me for while, so I figured I'd vent and get feedback....

Colony ships are cheap. Very cheap. Too cheap, IMO. Thus, extremely rapid expansion and development.

I'm curious to see how a game would develop if colony ships were more expensive (specifically, the colony module). But this is where things get murky for me. Since I have neither the time nor patience to experiment with the cost of colony modules, I'm leaving this open for discussion. From where I'm sitting, one could increase the cost of a colony module from anywhere from double to (an extreme of) ten times the current cost in all resources.

This has probably been discussed before-- has anyone actually tried a mod where the colony modules were buck-expensive (where everything else is unchanged)?
