I was playing a standard map where the AI had several Titanic Castles at the top. It even dug up a Grail. I took one of these Castles, and it came after me with SUCH a powerful army that I was completely overwhelmed.
There were tons of Giants, thankfully not Titans.
So, I destroyed the catapult and retreated for a while. The Giants were helplessly milling around and shooting at the Towers.
Conclusion: Cyclops, the Ballistics skill, and the Earthquake and Teleport spells (with a developed Water magic skill) are the key!
