Installed last night and had a new campaign as Rome on Hard.
The Etruscan League had some of its units at 1.5 (so as my starting units) but some of their garrison was still at 160 men (Italian Spearmen). Nonetheless, they fought pretty well and didn't break early.
I crushed the Etruscans pretty quickly but they recruited more units than they did in the past, so it wasn't easier as it was before.
Units walking one the battlefield get tired pretty quickly, and once they get in melee they become exhausted a bit too fast. Well, at least it's a change from vanilla where they could run across the map, fight and stay fresh ^^
I'll keep updating as my campaign gets going.
