Because it depends on how you play. For example, I typically play the following setup: Emperor - Marathon - Huge - Continents - 19 Civs If I change it up, it's typically to increase the difficulty or to play Pangaea/Fractal. In games like this, there are a couple of things to consider: The AI has a Scout already, they are likely to beat you to most ruins You will almost certainly start next to several AI's (lots of Scouts, lots of potential rushes) It will take you 12-18 turns to build a Scout It will take a bit longer to build a Warrior You will almost certainly get rushed early by multiple AI's A Warrior can help more with early rushes than a Scout. Your starting Warrior will, if he's lucky, find the nearby ruins. These are all you're likely to get, considering the AI starts with a Scout. Here a Warrior seems better to me than a Scout. I still may build one later to map out the world, but I tend to do that at the same time I'm killing anything that moves, so it depends.
