In Gem v1.13 I fixed a bug causing unintentionally high unit maintenance through an unknown, hidden modifier on total national maintenance in the game core code. This was a far-reaching effect, so we will need a cascade of adjustments to balance the sudden increase in gold income. I used this opportunity to address several concerns people discussed with gold income in the past.
The old unit maintenance formula depended on cost and strength, but cost is 10 times strength for most units in the mod right now, so I changed the formula to simply depend on cost.
I brought the ratio of unit to building maintenance closer together, so empires with a small military won't overflow with excess gold anymore. I removed the modifier for early unit and building maintenance, so early items follow the same formula as later items. This will avoid potential balance problems between wide and tall empires.
I changed villages back to 2:c5gold: and moved them earlier in the tech tree to help pay for higher early maintenance costs, and slightly increased national gold. This gives us lower science, so I buffed science buildings. I originally added science to villages out of concern that most science came from undeveloped population. Adding the Mentors Hall building fixed that problem more effectively. The experiment with village science is no longer necessary, and villages only provided ~10% of total research anyway, so I feel it's better to focus them back on gold.
