Regarding resource lines: The feature is ok. It helped show good resources that were off in the distance. When building elementary quarries, it was a bit of a distraction with so many lines going off in directions, especially when selecting the quarry for a specific element. I didn't really use the feature to often because most of the time I already had picked what I was building and where I was planning on building it.
I'm not a huge fan of this addition. Despite the player still deciding what to build, it's too close to playing the game for the player. I can see how its a useful feature for newer players, I find it detracts from the importance of the map itself. Since the map is overshadowed by the resource interface, anything that makes the map less important is probably not a good thing. Also, during each game, there are so few claim/building decisions that have to be made. Players should be paying attention to which resources are available on the map, where they are located, and if they are still available instead of being guided to decisions because each decision made is crucial.
