I was going for a domination victory on a small map (as the Inca) the other night, and what with my limited economy & huge army, stumbled onto something kind of useful. As my army was marching through Egypt and taking city after city, I finished my research on steel and went to upgrade my pretty big stack of catapults to cannon. Well, I was a bit short on funds, and wound up only being able to upgrade about half the stack. So here I am with an army of cavalry, riflemen, cannon, and....catapults!
I had originally intended to just suicidie my catapults into the next city I got to, but changed my mind at the last minute and decided to barrage with them instead. Guess what? A stack of 7 catapults (about half with the barrage I promotion) was just enough to wipe out a city's defenses in one turn, up to 80%. So each city was a rerun of the same thing--walk up to the city walls, let loose with the catapults to ruin the defenses, charge with the cannon to soften up the defenders, and mop up any survivors with the riflemen/cavalry. Worked like a charm, even after the Egyptians starting fielding riflemen of their own.
Just wanted to pass this on. If you can't afford to upgrade everything, keep some catapults around in the mid-game.
