Ages, eh? Reminds me of Anacreon... too bad SE4/5 won't let planets have individual tech levels no greater than the overall level of your empire... that would be sweet - only the most developed worlds could build your fanciest ships... however, MOO3 did something not quite the same but similar which might be replicable SE5 (maybe even SE4 in some scaled down fashion) - each hull size required an additional type of spaceyard be present on the planet, so for instance a Cruiser might require 5 types of yards, while a Battleship might require 7. I imagine something like this could be done in SE by means of spaceyard expansions with quadratically growing growing build rates and exponentially growing costs, tweaked with the right factors (e.g. rate 1K, 4K, 9K, 16K; cost 1K, 5K, 25K, 125K)
