What I want to get from exploration is the pure resource nodes, and more concentrated late game resources. At the moment things like Bauxite, Quartz and Caterium is rather far away from all my factories, so want to create something in the north that is closer to these resources. Also getting as many hard drives as possible. Some of the alternative recipes are great to create very large amount of resources from not all that many products. They seem to add to the overall efficiency and improvement of my base. And then there is the issue of Oil. At the moment the closest oil I have is about 2km away from my main area, and only provides 720 resources per minute. In the north there is an oil field that yields over 3000 resources per minute, so want to build a massive oil refinery there. And put the trains to good use then transporting all the good around.
I have indeed discovered the awesomesness of the hyper tube cannon! I saw a Youtuber build a crazy contraption our of those hyper tubes, and I had to try it.
