I just d/led and played this twice.
It's very impressive for a first effort, sincerely, but the balance is non-existant. I started a game on Monarchy (epic, large, continents) and after my first couple axe-men had 3 of your doubled city attack bonuses while the army formed I could see that was game, wiping out 2 civs and set up to storm over the world by 500BC.
So I restarted on Emporer (epic, large, archipelago snaky continents) and just gave up now at about 500AD, with over 20 cities and the world clearly conquered.
It's these doubled bonuses. The computer can't deal with em. My first axe-man was level 9 and literally unstoppable, let alone the rest of em. The adepts coming out with 2 movement, 70% withdrawal and 100% collateral damage out the gate in 3 turns apiece on epic is insane.
This was without reading the techs or civics or having any idea at all of what's going on. With that understanding this would be easily beatable on deity. And thus, unfortunately not much fun SP. The AI coding options coming with the patch would probably be able to rectify this.
World be a blast against other human players at the moment, but finding skilled human players keen to sit down with me for a 10 hour game of this mod is not something that's gonna happen.
Nice effort. Was very refreshing. I look forward to trying it again in 3 months to see how the playability has come along.
