Wow... This is one of the best mods I have ever played: a lot of new useful units, interesting technologies, etc...
Anyway, I still managed to discover few irritating details:
* When you build city improvements like mines and Forges the city becomes way more powerful, I got my capital to produce 250 shields in first era, while other cities only produce 10-15... That's annoying, because you can build any wonder in few turns and/or create huge armies and take over any other civilization.
* Treasure? Again, what's the deal?
* Some units are very similar like amazone and warrior, so why bother to build warrior if I can have amazone army...
* There is a unit (i forgot its name) which has attack/defense 2 2, but can travel on any terrain as it have been a road.
* What's the deal with civil disorder... When my city grows up to 5-7, the turn to disorder and I can't do anything about it, because I can't manage citizens and convert them to entertainers. I don't mind having slow grown rate, and huge city disorder levels, but at least give me some chance to fight with it.
* Well, on road any unit can travel 6 moves - I think, that's a great idea, but also, because roads are so powerful, I think building it (and also other improvements) should tame more time.
Despite all critics above, this is really a GREAT mod.
