Military units (ramping and promotions)
In general, I like the idea of military units costing more the more you have of them. HOWEVER, I feel this penalises larger empires a bit TOO much, and I think that this should perhaps be rethought a bit.
One suggestion I have for that is tying the ramp-up costs to a relationship between population levels (or cities) and units, or between soldiers and population in the demographics.
The upgrade costs get absolutely ridiculous after just a few units. I'd really appreciate a bit of a tone-down in those costs, as replacing them by building new units is... tedious to say the least.
Maybe... A possible solution is to have a hammer option for upgrading units, adding that cost to the queue of the nearest city? I've no idea how that could be implemented, but you geniuses can surely work that out
About promotions: is it at all possible to have a "retrain" option for units, to get XP and promotions from cities that build the relevant building AFTER the unit is built?
Example: City builds warrior; city builds barracks; warrior retrains at city with barracks; warrior now has 2 XP and gets a promotion (and everyone is
Great work on the mod, I hope it's still being worked on!
