New things often times have something called a "learning curve" which is the level of knowledge required to learn what ever it is. Well, KSP does not have a learning curve. KSP has a learning wall, as many have stated. Meaning the learning curve is so steep it seems like a wall rather than a curve. This thread is to discuss exactly what was so hard for you to learn just starting out, or what mainly was your "learning wall." What was the first thing that frustrated you? Or the first thing you needed lots of help to accomplish? I'll start us off. My learning wall was maneuver nodes. I was first taught to eyeball everything, eyeball getting into orbit, eyeball mun transfers, eyeball trajectories to the mun, and eyeballing landing. Thank goodness I discovered maneuver nodes and the navball, which made everything a whole lot simpler. Now lets hear yours!
