In my current game I'm crapping my pants for Atilla. I play a Scrambled Earth map as Netherlands and am located in Panama. West USA has Venice, East USA has Atilla. In South America I have the Maya and India, neither of which pose a threat. Anyway, I have Groningen placed in what is pretty much Texas, and Nijmegen a good bit north of that, close to Venice (who is my ally). Atilla covers the entire East Coast with his 6 cities.
I sent a Chariot Archer to scout his army a bit. 6 Trebuchets, 8 Longswordsmen, 5 Crossbows, a few Horse Archers...and that was what I could count. And he's moving his army towards Groningen. All I got there is a set of walls, a Crossbow and two Pikes...I'm scared...
And that is on KING >.< So yeah, he can definitely pull off something.
