For my mod I thought it was a good idea to make a special cheap unit to make resource colonies. You know, the ones that connect a resource to your empire but eat up a worker. So do you: - build them a lot... - build them rarely, for Iron (or luxuries/strategic resources) - would build them more, if the cost would be lower. I was wondering if anyone ever made these... because I don't. The reason is because you need to build a long road far away (which are a lot of worker turns) and then it costs you a worker. I figure I might as well build a city there.
