Hey guys this is really a great mod, i personally prefer it over sevomod and the vanilla version. The game feels and looks alot better !
One thing i noticed:
I started the world map as Germans on Prince level (my usual difficult). As i had alot of neighbors i ran out of free space very soon so i switched to warmonger mode and started to conquer several towns. My army was to big to maintain it permanent. So i burned alot of them in an final assault on rome. After that my unit upkeep was nearly at zero but i still made alot deficit. The City maintenance made me bankrupt, even with research at 0% and maxing out the commerce in all cities it was at -11 gold per turn. The only income that had kept me alive all the time were the loot from the conquered cities. I checked out the AIs with the world builder and noone of them expanded beyond 5 cities, even when they had plenty of space to do so.
I didnt continued to play as i couldnt raze any cities nor i could find a way out of this financial dilemma. I have had 9 cities to maintain at that point, isnt it supposed to have that much cities in the ancient age or did i something wrong ?
Oh and i have some small suggestions too
I very much like the submarine bonus vs. various ships. Very realistic !
How about a new tech named 'Sensors' which will include Radar and Sonar systems.
This could bring a promotion for the destroyers.
like 'ASW' (Anti Submarine Warfare) +25% vs. all Subs
Its like in WWII. In the beginning the allies didnt had much chances to catch the german subs. Later on when the Sonar systems got improved it was alot easier for the destroyers to hunt down the subs.
Also adding +1 visibility for all modern ships with the developement of Radar would make sense.
About the slave revolts. Very nice idea but they just happen to often. In my case every 2nd or 3rd turn a rebel attacked one or more of my cities. My garrison forces got alot XP just by beating these morons

This feature could be exploited to produce super hero units.
You may also check out the
revolution mod. It gives a really nice addition to the game feeling. The rebellions and barbarians are not only in the ancient times a problem but throughout the whole game.
keep up the good work lads, cant wait for the next update
