Umm... I wasn't exactly sure where to put this. But I've been playing Sins and got the point where I wasn't useing logistic spots on most planets. I'd put the basics, a refinery, comm tower, and a trading port. But more then that I simply didn't need. I had a select few planets that could churn out all the ships I'd ever need, and I had all the tech stations I'd need. So I simply didn't use up all my logistic spots. So I came up with an idea, why not add like another logistic building to all the factions. A sort of orbital colony that'd produce extra income. So when you get to the point where you have nothing to build, you can just build those colonies.
