It's been a while since I played these games. With settlers 1 and 2, a major portion of the game was managing the transport of resources. That meant setting up strict pathways and even blocking some resources from going down some paths to setup a "priory" route for shipping important goods.

I believe Settlers.. 3? got rid of that completely. Instead of manually placing paths and controlling the shipping routes the game would just figure it out for you.
