Cons
Con Some visuals are poorly done
While the rockets, buildings, and even the Kerbals look pretty good, the environments and particle effects are a bit lacking.
Con Steep learning curve
Kerbal Space Program is not really a pick up and play title. It can take hours just go grasp the basics and the game will keep throwing new concepts at you as you progress into space, even stuff like orbital dynamics. Because of this, it can easily take dozens of hours to truly master this game.
