I think what would happen is Agristocracy would get ignored by everyone while Financial civs would run a 50/50 Riverside Farm/Cottage while in CS/Slavery/Agrarian which flips to Conquest during a military buildup phase. It feels like the right kind of idea though. Edit: While we're talking about Slavery, I think it could do with a +50% Worker rate. Edit2: UncleJJs take would mean Agristocracy works in its current form for Financial civs as long as their farms were beside a river, making the strategy more exclusive AND more dependent on the starting position RNG. Aristocracy, Sacfice the Weak, Slavery, Conquest would be exceptionally powerful after Sanitation was researched. Flauros would be pleased. He could farm over everything for his +4/+5 gold per tile, and every tile positive food.
