@Tomice, in vanilla caravans are 75, and the cargo ship is 100 I believe. In the mod there's a much better cost disparity for the value they generate. @Thal, I'm not so worried about the barbarians raiding them, I'm more referring to the AI warring/raiding them. It's possible I need to move up a difficulty and will be satisfied as I've been usually testing lower to get a feel for features as they are added. But I would still say that some danger to intercontintental routes helps put a premium on secure land routes. Barbarians raiding them is really lame of course, but it does mean I'm less likely to send a route out into the unknown or unclear/unsecured area early on. The effective lack of danger later essentially means the cost of protecting routes is much lower such that it is always much more profitable.
