Has anyone ever looked at the logic for barbarian spawning? Does the logic decide that it wants to spawn a barb first, and then look for an appropriate place to do so (if one exists)? Or does it loop through the tiles looking for a legal place to spawn a barb, and then deciding whether to spawn one or not? Basically, I'm wondering if keeping extended visibility over your local region of the map would cause barbarians to spawn more frequently near other civs (because the game commits to spawning a barb, then finds an open tile to do it). Or if having such visibility just effectively reduces the likelihood of barbarians spawning at all (because there are fewer chances for a barb to spawn).
