Hehe. I was just playing. I am all for tweaking the economic factors of the game. Although there are times that I just want a military game too, so I hope that if this stuff is added it's optional. I just don't know if I want to have to build houses for all my people on top of everything else we already have to control. At least not all the time.
A few suggestions to allow some of this stuff without requiring it.
1. Don't change the current population/cargo/facilities limits, but DO allow some kind of population expansion facility to be modded in that will change the max population allowed the way cargo facilities can be now.
2. Add a population happiness value that is triggered when planetary population is at maximum. By default leave it zero, but this would allow mods to change this and have overpopulation become a real concern.
3. Add an ability for facilites that will allow them to not count against the facliity limits of a planet. This could be used for subteranean facilities, or for "Cloud Cities". (Anybody ever wonder why you can build a facility on a Gas Giant but can't build the same facility in the atmosphere of a rock planet? I do.
) Even better than that would be some kind of "Facility Complex" which would count as one facility, but allow you to put a fixed number of "Sub-Facilities" within it. You could almost do this the same way you do ships and stuff now. Have a "complex" design file with different size complexes would allow different facilities, and each sub-faclility would be like a component. If you wanted to change one of the facilities, you could make a new facility complex design and "upgrade" it. "Urban Planning" SEIV style.
But again, make it moddable but not required.
