Hi, I'm not exactly new to this forum, been reading since I first played civ4, but never registered. I'm playing RoM AND (started about one year ago) and seeing how you all struggle to improve the game I couldn't resist
Regarding maximhar's post: Barter Economy seems overpowered, especially combined with State Church (if I'm not mistaken), which gives +25% gold per each religious wonder (Mahabodhi, Church of Nativity etc.) and Patrician (+1 gold per specialist). I was playing Mayans, Standard map size, 7 players, Monarch difficulty level. After building a new city (about a year 1000 BC) I was able to build 20 buildings (big ones, like courthouse or port) in 50 turns. I think it works this way when you play as a civilization starting with Ritualism tech and with small number of civs (you can get to Hellenism, Naghualism and Confucianism before others). I used a strategy of not founding new cities before I had 8 religions in the capital, it worked surprisingly well, I was able to build every wonder in about 15 turns (still Eternity game speed). The Oracle and Cheomseongdae can be helpful if you smash the other civs before they start.
Therefore: I think Barter should have more drawbacks (if I remember correctly, it adds +100% to distance maintenance). This is quite realistic (the main drawback of Barter Economy in real life are ridiculously high transaction costs - because of lack of currency, you cannot calculate or compare prices - imagine you have a book and you want an apple, you have to find a person who needs a book and has an apple; in reality there were certain days in certain places where people could trade certain goods, for example trading meat and livestock every month or some items were considered to be money - special shells in Far East, jewellery nearly everywhere, different metals, copper, silver, gold etc., but still people were using useful materials as a mean of exchange).
Conclusion: Perhaps Barter should have higher costs, not only distance maintenance, but albo number of cities. I don't know what do you think or if it can be done to look realistic (small economies could collapse because of +900% maintenance), but with science slider at 100% for the entire length of the game (Space Race victory) and income +150 per turn in 1000 BC and +2000 per turn in 1800 AD the game becomes too easy for the player. Leave the State Church and Patrician, they are balanced, but Barter is just too powerful. It would be less overpowered, if you could add significant number of cities maintenance - as the empire begins to spread, it is increasingly difficult to manage economy and production because of high transactions costs - does it make sense?
P.S.: I like the mod, Afforess and my post is not meant to criticize you
