For example, a Gallic 20 unit force versus my Julii 20 unit force equates to say a 850 versus 650 troop battle respectively.

I can destroy their army with losing about 150 soldiers. I know the Romans were good, and I know that they did win battles that easy, however, there were battles where the Romans were annihilated. At the Caudine Forks, a rebel army of Samnite hillmen humiliated a Roman garrison styled force.

This doesn't happen in RTW. The only way of losing a battle is with intentionally stupid tactics or by pressing the AutoCalc button.

If the enemies would fight with more determination, then the game would be alot more realistic.

I fought a Germanic "horde" in an ambush against me where I was heavily outnumbered. They retreated very easily onve I could get in around their spearmen with my cavalry.

I think that the routing happens too easily. Germanic tribes in reality were notoriously tough and determined.

I hope CA solve this "routing" problem firstly, then we can look at epic sized battles as something to really get our thinking caps on and act like real tactical generals.
