I am really excited about this DLC. Some people here seem to underestimate how much effort is necessary to create a comprehensive, integrated, and physically accurate robotics system. I'm amazed to see such a complicated and impressive new feature being released alongside a cargo system, surface features, and a whole new way to get science (perhaps along with other as-yet-unknown features). I'm confident that these new features will come with the same intuitive and easy use we've seen from features like delta-v readouts and the maneuver node system. Great job, Squad!
In fact, when I saw the announcement for this expansion, I was almost surprised at how inexpensive it is. I've only played for a few hundred hours, but I'm more than happy to pay $15 for this massive update to an incredible game.
I also love the new suit. It's an awesome look for the Kerbals.
