I just found this mod Sunday, so I'm really new, but. . .
So far, my favorite unit is the Ptol Royal Guard phalanx unit. My Saba royal army encountered one unit of them and one Ptol general @ Memphis. I could only see the general before I assaulted the town. He was easy enough to kill, but those royal guards took all of my missile attacks (slingers, archers, javelins), then melee with 2 of my generals and 2 units of bribed galatian swordsmen. They stayed in phalanx formation, surrounded, until they got down to ~20 men left, then they switched to swords and fought on for another 10~15 minutes! They almost won the battle by timing it out!
Very much looking forward to "meeting" the rest of the factions in this INCREDIBLE mod
