The mod is very very good but some things:
*You may get an error from Daedalus, the error is at Art/Units/Daedalus, the file dEAdalusdeath.flc should be dAEdalusdeath.flc
*The crossbow cost is too low, only 15, for a unit of 4atc and 1def, while the Ranger costs too much: 40 for 3atc and 1def. The Man on arms costs 40 for 5atc and 1def, and i think that should be a base for others. This way you upgrade ranger for crossbow without cost
*The Arrow Tower is too good, 10 def is too much to ancient era, if you build one you wont lose your city until modern age. For ancient times 5 def is already high, same for rampant cannon, also change the costs so the upgrade is not 0. Like Knight costs 70, Heavy Knight too, you may upgrade freely to a much better unit, increase Heavy Knight cost to 75 or 80. (Also remember the Cuirasser that dont have cost, 75 or 80 should be good)
As you noticed I dont like upgrade cost 0

This is because you may build a lot of crap units and at one turn transform that to very good units, its too dangerous. The same thing is happening with Early submarine and Submarine, if you want to show that now we build a better sub with lower cost, I advise turning off the upgrade ability for early sub.
Congratulations on the mod, i loved the new civs, new units, and etc. Keep the good work
