I used to stack tons of factories on my colonies to promote fast construction on tiles, but now that seems counterproductive.
Now I build a space elevator, deep core mine, and spaceport; the latter if I've built or placed a shipyard. And that's it. Seems that I have to use citizens to really get work done.
It also seems counterproductive to specialize any particular colony toward research or income. Again, it seems that I have to enslave employ citizens for that extra "grease" to get things done.
Got any advice for new colony managers who still want to specialize?
