The gameplay of Kerbal Space Program (KSP) is widely praised for its unique blend of fun and education, particularly in teaching players about orbital mechanics and rocketry. Players engage in building and launching spacecraft while navigating realistic physics, which fosters a deep understanding of complex concepts like delta-v, thrust-to-weight ratios, and gravity assists. The game features a variety of modes, including sandbox and career, and is supported by a robust modding community that enhances replayability and introduces new mechanics, making it a compelling experience for both casual gamers and space enthusiasts alike.
- “It masterfully combines realistic physics with accessible gameplay, allowing players to design, build, and launch their own spacecraft while exploring the intricacies of orbital mechanics.”
- “This game has taught me more about things like delta-v, inertia, friction, atmospheric pressure, atmospheric density, gravity, orbital mechanics, orbital maneuvering, and more, much better than any science or college class ever will.”
- “Its unique blend of realistic physics, engaging gameplay, and endless possibilities makes it an essential experience for anyone interested in space, engineering, or simply enjoying a deep, rewarding game.”
- “The gameplay itself has gotten progressively more solid as the years have progressed seeing more gameplay functionality, additions to the world that add more enjoyment to the simple sensation of exploration and growth of your space faring company and research center.”
- “The game has a steep learning curve to understand certain mechanics or building techniques but when you learn how to control maneuver nodes or design good rockets the game becomes simple.”
- “The physics follow the actual laws of physics so there is no 'handwavium super magic space drives' involved, this is a realistic simulation (even if the solar system and planets are scaled-down versions of our own, the laws of physics remain the same) involving a lot of planning and a lot of learning about how orbital mechanics and rockets work.”

The atmosphere in Kerbal Space Program is a blend of educational and entertaining elements, providing players with a realistic simulation of atmospheric physics and rocket mechanics. Players often experience a mix of frustration and exhilaration as they navigate the challenges of launching rockets, managing atmospheric drag, and executing successful re-entries, all while enjoying the humorous antics of the game's kerbals. The game fosters a sense of accomplishment as players learn from failures and gradually master the complexities of space and atmospheric flight.

- “The atmosphere of daily minutia holds you back and keeps you from becoming your best self.”
- “The game is hard to learn, the learning curve is steep because although the build system is seemingly simple and the planets are small enough to be friendly (smaller atmospheres, slower orbital speeds), the aerodynamic model is incredibly intricate and the physics engine scarcely pulls its punches.”

- “KSP 1 has much better performance, and if you want to make it look better, just use mods.”
- “The game has been released as a full version for some time now, got an engine update, huge performance improvements, bug eradication, a ton of new features, and the community is as vibrant as alpha and beta stages, with lots of constantly updated and maintained mods.”
- “Moreover, the game's computational demands can sometimes lead to performance bottlenecks, especially when simulating complex orbital mechanics or rendering intricate spacecraft designs.”
- “The biggest problem with the game is the poor optimization of certain aspects like time warps and the high quantity of objects in space.”

The grinding aspect of the game is widely regarded as both tedious and time-consuming, particularly in career mode, where players often feel they need "a second life" to manage the repetitive tasks required for progression.

- “Playing with rockets that go boom most of the time trying to go further each time you installed the game and losing interest when you just can't reach that planet or moon you have been grinding for the past weeks, only to try again a couple of months later because you still think you can do it if you just try again and again.”
- “Repetitive tasks: grinding resources and completing contracts can feel monotonous after a while.”
- “The career mode feels a bit grindy and boring; science mode is my preferred mode, as you don't instantly have like a million parts at your disposal, which is what sandbox feels like.”

- “I used to love this game, then they broke it by adding their own crappy launcher just to launch KSP, this launcher wasn't asked for and is full of advertisements for their other games.”
- “Game now comes with its own bloatware launcher, increasing the already horrible load times, harvesting user data without asking, all while shoving ads in your face and bricking the performance of a game already heavy to run.”
