Finished a game yesterday, won on domination on 900AD. Played Phoenecian (Hiram), Monarch, Earth2 standard, epic.
Some bugs: 1. roman roads and railroads do not have the benefits of a road or a path (no +f or 1h or 1c). I constructed Via Apia and saw my prod food and commerce plunge
2. you can change a path into a road but not the other way
Remarks:
1. AI do not give any importance to religion, I founded all religion but 2, without beelining at all. I could have founded all of them but did not want to because I preferred to have more religious diversity and feared to run short of Great Prophets ;-).
2. Wonders are too cheap. OK, It helped to be Hiram, but still, some time with the right civic, resource and leader it is faster to build a wonder than a market. Things get even worse towards the end where production is just too cheap.
3. Barbarian are a threat very early (spears and 4 strength archer appear fast) but they do not keep up, you should send horse archers and axes faster. When I discovered the Americas, I havent seen any force above 4.
4. Resource less sea tiles are now just too much underpowered (given the prod, food and comm. Bonus via road).
5. Lumber mills are too powerful. You should either delay their availability or lessen their bonuses.
My games was challenging a little bit in the begining (Mongols attacked me very early and well, they almost took one of my cities and I had to build a lot of troops and bring in Brazil to hold them), but was really easy after that.
