Another piece of advice for building an early SoD is to share food resources among a tightly gathered core of 5-7 cities. Once you hit that population cap, you won't need the 2-3 big food resources you hopefully found for your capital. So share them (and the

they generate via slavery) by building cities very close to the capital. This keeps upkeep costs down, reduces the strain on workers, and does so without sacrificing early growth, production potential of either city (when done appropriately). I've included a picture of what this looks like in practice. The game is Emperor level, and from the point pictured (just when I've hooked up iron to make Praetorians, sword replacement, str 8) I would go on to melee rush my one continental neighbor in a very rapid early demise for mother Russia. Note how I've got four cities practically on top of one another...that's quite deliberate. The one city in the NE is there to get revenue from Gems (An entire continent in the classic period benefits greatly from income producing resources) and to provide a good location from whence to launch a flank attack as Catherine's defenses focus on the main invasion from the south.
