Costly ship upgrading, but with dramatically higher fleet cap

[Philthy]

What's the best way to make a mod where the cost to upgrade ships is something like 15 times higher than it is now, while the fleet cap grows dramatically more quickly?

Should I tie it to some sort of starting techs?

Just edit the Defines. FLEET_UPGRADE_MINERAL_COST_MULT, NAVY_SIZE_BASE, NAVY_SIZE_POP_MULT, NAVY_SIZE_SPACEPORT_BASE, NAVY_SIZE_SPACEPORT_MULT are probably what you're looking for.

Thanks! I'm curious about how the game plays if you just flat out can't upgrade old ships without paying through the nose.
