Correct. The big early problem is paying real estate costs. Hence Asoka for cheap courthouses. A small highlands is the first smallish map where the player can reasonably expect both currency and metal casting from huts. Although I've been playing them without either writing or metal casting. (Strategy Oracles metal casting.) At standard speed, and standard size map, a non-financial civ can reach a speed of 1 tech per turn (3 religious wonder economy) around 0 AD and be in, or close to, state property. At that rate corps won't matter. Nearly the whole spaceship can be chopped. Fast workers anybody? Asoka is lethal. Currently I'm testing a standard sized map. With an early engineer as part of the strategy, I am wondering about Oracling divine right and engineering either the AP or Spiral Minaret. Currently I've used that engineer for the Ironworks and a 2nd one for Mining Inc. If state property is used the National Park is a consideration.
