This is just a small mod which takes the maintenance feature from my other mod, but doesn't include any of the other changes I'm experimenting with.
All this mod does is: removes all maintenance from buildings, adds 3 maintenance cost to Colony capitals, and makes LEP take the form of and extra 0.2 maintenance per colony per colony. This should make rapid expansion more difficult, reduce the penalties on staying small somewhat, and counter some of the advantages of a large empire more effectively.
Based on the 1.03 files.
I'm not intending to make any further alterations to this, but will try to keep it up to date with the latest released patches (not doing opt-ins as well, it takes too long).
