So my good friend, I've tested the Dacians like 50 years or so.
you have done an amazing job, but there still a lot of work ahead of you. Now i will only write the bigger details of what is most important:
I've played hard/hard
As a faction the Dacians starts good. They are balanced and the game is easy in the binging. you can conquer very easy a lot of cities nearby because they are very poorly defended (most of them has only 3 ilyrians mercenarys units and you can conquer almost all the cities nearby with only recruiting a few mercenaries. SO that has to be improve a lot..
* The capital (sarmizegetusa) is perfectly placed on the map but the other city Porolissum is a disaster. In the history that city did not exist it was a Roman name for a camp they build after the Dacins war 107 AD. So that we have to change
*The dacians family tree should improve, the faction leader should be at least 15 years younger because of the age of his sons and he has to have a daughter as well.. 3 sons and a daughter..
* On the minimap there are 2 dacians provinces, One you start with witch is correct but the other one to the est is a rebel faction called dacia as well. The minimap is a disaster by the way.
* Government building , I believe the barbarians faction should stop growing after reaching a minor city. (Just like RTR platinum 1.9 witch is the best out there mode i belive ) Other ways you have to change the in game pictures for the bigger barbarian city's. and the building should take alot longer to construct. A lot longer. now after 4 turns you can get all the units witch is making the game very boring...
* The city names around Dacia are horrible. As a very passionate historian I can tell you that 90% of them did not even exits and are places total scrappy on the map. For example the city near the black sea is called Tomi
? There was a greek city called Tomis around there so many names have to changed. Luckily i might help you with that.....
So the campaign map looks ok. The dacians gets strong quickly and there only danger are the macedonians so stay away from them... I like that actually. The Thracians are far inferior and they don't really bother you. They have problems of their owns with other factions...
I will test them later, but they looked ok as well from the AI point of view (me playing the dacians).
A big bug in on the map is a little lake between dacians and ilyrians (todays hungary) where there is a rebel naval ship going nowhere. It's actually quite funny: the war fleet caught in a little lake for no reason at all.
Ah one more thing: the rebel factions is quite aggressive, there are a lot rebels showing up almost every year, witch can be funny sometimes.. The diplomacy between faction needs a change. Every diplomat offers you their map in exchanged for money. and they all ask for alliances witch is stupid. a diplomat should not be able to talk to a city, i believe, if there is no governor with diplomacy skills.or with a army without a leader with diplomacy skills, they should only be able to bribe them or not. that will make the game more interesting.
There should only be 1 Roman faction.. They are just in the way of each otherwise. and they should have it hard from the start, fighting rebels, greek and gauls other way they conquer everything to easy
