Well, I had to change the attack type "batter" to some other one(as ultifd already suggested, I rewrote it to impact attack type as a replacement),but I was able to play some games with this faction.
I feel it's a integrally a good faction - if I don't mind on it's historical accuracy -.
I think the peltastai and the psiloi units are well done in both animation and modeling, especially psiloi,I like it's animation.
but If I consider about balancing, I think this faction is a bit overpowered as like other factions you have been made so far. especially the atlas is a too powerful unit as it has devastating attack and 2000 hp with regeneration and stone armor type. you should raise it's cost or make it more weaker.
I think "calvary" is a misstype(or is it french?). you should rename it as "cavalry".
The buildings are generally well done,I think. but I feel more of a medieval feelings than a classic-greeks from these buildings(probably the castle and the tower models cause the medieval feelings in this faction.I suggest you reconsider their textures or remodel them).
And it seems these buildings use too many unnecessarily large textures.you should decrease these texture sizes and pack them in a single file.
I feel a bit ? about the trojan_horse's appearance of this faction,because I thought trojan horse was made by the wood,like this.
but trojan horse in this faction looks like made by the metal or bronze.
I don't want to nag about historical accuracy about units appearances, but I must say the hoplite's appearance should changed. because the hoplites in this faction have shield with the lambda sign, so I assume they are spartan hoplites, because the lambda sign in shields was used by Lakedaimons(spartans). but they don't look like spartans,they wear something like Thracian helmet and they don't have beard - spartans had long beard and hair - . so you should change their looks more like spartans(you should change the helm to Corinthian helmet and have them long hair and beard, then it would be looks like spartans), or simply change the shield's sign.
sorry for long post,I have enjoyed this faction.keep up the good work.
