1. The pillage economy. (Requires a friend on multiplayer). Very simple: you play with your friend and you declare war on them! Sounds like an unfriendly thing to do. But the idea is this: every time you pillage a pasture, you get 50-75 gold. It takes NOTHING to repair damage. So you declare war on your friend and you and your friend pillage one another's territories. Every turn after the pillage, both of you will repair the damage from the pillage with a builder. And then they can pillage that improvement again! Lots of free gold for everyone. 2. The "Sack My Capital City" strategy. Also very simple: Play as the Persians on Diety and have Sumer spawn next to you (not hard- they traditionally spawn together). Beeline for archery and build slingers to upgrade. DON'T PROTECT YOUR CAPITAL CITY. On Diety, Sumer oftentimes does an early rush with war chariots. Get 3 or 4 archers and a warrior (and make sure you have a second city somewhere), but LET SUMER TAKE YOUR CAPITAL. This triggers an emergency. 1200 gold to recapture your capital. So now recapture your capital with your archers and warrior, and now you have 1200 gold in the ancient era. Then beeline for Iron working. Spam warriors, and use the 1200 gold to convert warriors to immortals. Win!
