Pros
Pro You can own an empire, not just a ship
You start in a small fighter or trade ship, but can own and control as many ships and stations as you care to build up, including some unique facilities tied to the story.
Pro Deep, open-ended gameplay
You can fight, build, trade, pirate - so much to do!
Pro Teaches orbital dynamics & rocket design fundamentals in an accessible manner
The physics engine does a reasonably accurate job of replicating the fundamentals behind both orbital dynamics and rocket design, so by going through the tutorials and experimenting, you're actually learning some real rocket science.
Pro Tons of stuff to do
Build rockets, space planes, space stations, rovers, landers, probes. Explore planets, moons, capture asteroids, set up a communications network, colonize a planet, mine for resources and much more. It can even simulate our solar system.
Pro Huge modding scene
There's a plethora of mods available that can change every single aspect of the game.
Pro Excellent construction sandbox for building and launching rockets
KSP at its core is a rocket building and launching sandbox. When creating a rocket you can place engines, fuel cells, structural elements, and even parachutes, allowing you to build a rocket in any shape and size. The end result can even look like a giant doughnut, which might be difficult to get it into outer space. Even if you fail, the entirety of the process is really enjoyable.
Pro Motivates you to learn
Kerbal Space Program puts into perspective how amazing the advancement of the human race is. It inspires you to learn our history, how we got here, and what we can do proceed.
Pro In constant development
KSP is a shinning example of early release done right. The currently available game is fun to play, and the developers are constantly adding new major additions.
Cons
Con Graphics look a bit dated compared to a game like Star Citizen
Con Daunting for new players
This series has a long pedigree. It has a lot of complexity that you get dropped into pretty quickly, and the plot has some quirks. If you don't mind sometimes checking out a wiki to wrap your head around something or to get unstuck, you'll be fine.
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.
