It was a learning curve at first I must admit, but the lack of a GUI in my opinion gives the machines a realistic feel, where you need to take into account the surrounding space and layout of your build. Later machines do have a GUI so it is a case of the lesser rudimentary machines being much more hands on.
However one thing that I find troublesome is the durability of the magnifying glass, that sucker breaks after only looking through it a couple of times. I end up just ignoring it and wrenching machines over and over to get what I want, and don’t talk to me about barrel contents… What happened to those shiny gem magnifying glasses?
