Sarmizegetusa was a breeze with the extra 20000 money. I instantly grew a population of about 5000 by doing massive building early on.

The last 2000 people were a tricky balance between labor force and my row of palaces. Tax income of 14000 / year isn't too bad! One thing I discovered on this level is that ballistas won't shoot from a "thick" wall--I had to keep my walls at a total thickness of only 3.
