3 things (apart from me loving the new units):
1) it seems that many units are recruited from the wrong barracks. Carthagenian archers are recruited from the infantry barracks, and for Bactria it's all over the place. I can recruit thorax pikemen from the first lvl of barracks, companion pikes from the royal stables and royal indian elephants, riders and other cav from the royal barracks. Also, you can use all roman general units from the start like imperial spears and the very powerful cav (sons of mars ore something) and praetorians. I have the 4tpy mod installed, but that shouldn't matter -right?
2) some units will see very little use. The phonecian pikemen for carthage have less armor than their predecessor african pikemen. I would only recruit them for fun - never if i needed to make every denarii count.
3) I wonder if every person asking for off-steam links are playing a pirated version of the game...
