Kerbal Space Program

The Cunt-Fuck 3000, containing roughly 20 kerbals, is en route to the Kerbol system's star. Godspeed.

Very fun game. starting the game might not be as fun but the more you play the funner it gets. I recommend starting with sandbox mode learning the game mechanics then jumping into career/science mode but sandbox is arguably the funner game mode. Very modable game and is so much fun with the 1000s of mods for this game.

I love this game like i love my monsters, not addicted but dedicated

very high content game, could do with some graphical improvements. very happy with my purchase. 4.5/5 stars

Kerbol is very bright, get graphics mod to make jebediah good looking, gmae is very addicting, my wife just left me after I reached to save bill kerman instead of her from falling into a river

This game will test the limits of your creativity and critical thinking. Be patient

pretty good game! i could see myself getting A LOT of hours in KSP in time cause this cause theres just so much to do, and so many diffrent air and space craft that you can try to build. there are still some bugs and glitches, but you dont need a good pc to run it. i dont think it is worth the $40's, but if its on sale, HECK YEAH!

One of the best games ever created in the category of "games that would be ideal to have on your computer if you were stranded on an island for 10 to 15 years".

Cult classic. Very dated graphics. Unfortunately doesn't run as well as it should with modern hardware because it's an old game. Still, incredibly fun and kept alive by the insane modding community. Highly worth it.

Don't play the sequel.

This gam made me vely smart. And after 240 hours I finally learned how to use staging, and how to leave atmosphere. I rate it a solid ksp1/ksp. Buy it or u explotana.

very good game and entertaining makes you feel like a good rocket engineer or scientist,

This game is in my top 5 games of best games ever.
If you like to build and explore, try this out. It's not a high score or instant gratification kind of game, though. Achieving your goals could take a while, but you'll have a lot of fun and probably learn a thing or two about space exploration in the process.

please note, i allegedly have 257 hours of playtime at the moment of writing this. 95% of those are from leaving ksp running so that i dont have to locate the correct game and save file when i come back to it the next day. i probably only have 5 or 6 hours at the time of writing this. but they are all worth it...

Fun but quite challenging. Definitely need the help of guides and other third party content to fully enjoy this game

amazing but technical game, I suggest doing some Youtube tutorials to figure out how everything works before you go crazy!

Download CKAN the second you buy the game, you will find mods in your game you dont even remember installing

this game is great for those who want to learn about orbital mechanics and rocketry, this game has taught me most of what i know about the game, its very hard for the first time but as you play longer and longer you will learn from mistakes and never fall for them again.

Good game planes and rockets and lil frog

First it makes you want to kys, then you learn about aerospace physics and engineering. 11/10.

Good game, insane mod support, fun, and replayable!

i love this game but after while sometimes you need a break but then your like you know what... i miss the mun and it sucks you back in and you want to create more and more complex stuff its a very good game some of the missions though kinda suck and repetive

frustrating but addicting, plus a little real life physics. great game overall.

I study aerospace engineering, honestly this game is really useful to visualise many of the maneuvers and effect of going into a heliocentric orbit and stuff like that. If you get really into it, it might also help you understand launch windows and round trip Hohmann transfer missions, of course this is all with a significantly reduced difficulty than real life, still quite cool.
I only play career mode so I can't speak for the other modes, but the tutorials are honestly really helpful and it's one of the only games which I would say the tutorial really explains some of the hardest parts of the game. For example achieving a rendezvous was conter-intuitive for me as simultaneously trying to match V and matching position seemed really complex.
The career mode is quite well made, starting with small rockets to play with and basically only the Kerbin orbit as possible missions from the game. Then you conquer the moons and land on them, get more science and progress through rocketry.
Eventually you venture out into the solar system and send out probes to other planets, after that you can finally send out maned missions to other planets and try to land on them. This is all a pretty reasonable mission profile in my opinion.
Yes the physics can get quite janky when you speed things up, water surface tension is extremely high so you very easily break everything when landing large crafts on water. Some missions forces you to collect data on extremely mountainous dark side surface parts of the moon and is almost impossible to do. Rockets tend to behave like snakes without many structural reinforcements, and they do weird things when they get too long. However all this as part of a game just makes it more fun and amusing to watch, and if it was a perfect simulation, I don't think nearly as many people would have enjoyed it.

A brief Summary about this game, you manage a space agency where the 2 hiring traits are courage and stupidity. this game is also best with mods.

KSP is my all time favorite game.
The greatest thing about games is learning STEM withouth realizing it.
In KSP you learn about DeltaV, Orbital Mechanics, Interplanetary transfers and so much more.
All of that combined with the great feeling of for example your first Mun Landing makes it hours upon hours of fun!

Harsh learning curve, but amazing game. Great mods as well.

Literally the most awesome game ever created. The best especially for those into physics, rockets, and overall aerospace, having it being based on real-life physics is the best part. It allows you think to think like a big boy/girl. Awesome stuff. SOOOO glad I got my hands on it. Highly highly HIGHLY recommend it! :D

REalistic fysics, exiting game, hidden "easter eggs" EVERYTHING!

I love KSP! Don't be afraid to fail, learn from mistakes and enjoy Scott Manley tutorials on YouTube

I like it T-boi! This is one of the best games I've ever played. I've been out of the game for many years and have always thought about this game, having played it many years ago. Just got a gaming laptop and the first game I downloaded and played was this gem. Do yourself a favor and play this game NOW!!!

This is an older game but still a lot of fun and educational

Ever wondered what it takes to get to space? This is the game for you.
Includes an extensive tutorial, and if you play in career mode with extra cash, it has missions that slowly introduce you to different missions.

Very cool game. Poor Jeb is stuck orbiting the sun tho. Other than that 10/10 game, would kill Val again

One of the best physics sims, even better with mods.
A staple experience for all space enthusiasts, and definitely worth a try.
The sequel has had/still has many problems(to say the very least).
But this game is and will always be a timeless and enjoyable classic.

10/10 kind of a grind pretty hard but some much fun along the way

Played for a while got to mun left kerbal want to other planet left onother kerbal, leavin kerbals on every planet new goal 10/10

this game is great it has so much to provide in the base game and there is so much more you can do with mods and this game has made me love space that much more

I think this game is single-handedly responsible for the new space race and dozens of new space companies. To put it simply: If you want to feel like one of the Space Billionaires without the slight drawback of having zero scruples and exploiting thousands of people, this game is for you. Though zero scruples are probably beneficial anyway, since you'll be watching Jeb collide with the ground quite a lot.
Also, it is extremely addictive despite still being buggy as hell.

Best way to learn Orbital Mechanics, and in a really fun way! The only thing missing is some Achievements/Trophies. Oh, and if you are thinking about buying KSP2 instead, don't. This is the game, the other is abandoned.

Dont know why I waited so long to play this. If you like engineering stuff for hours (and then blowing up anyway) all in the glory of the cosmos, this game is for you

one of the best game to ever exist (within game go to "community" and add mods). This game is good ~100 hours play on it's own and it's infinite with ~20 core mods. With that said - installing mods is not exactly easy and is a game in itself as not all mods are compatible with the current version. So - make a "stable copy" folder of the game before adding new mods.
I have only 11 hours on this account, but I just came back after ~5 years break. This game is truly amazing. ..again - with mods, it's like EVE online (minus the online part 😂), but you build all the shit yourself. Like - literally. Like lego. And there's planets/muns exploration.

Ecxelent game! I wanted this game since years ago, and now i have it. Thanks to the hero who put the game in -75% now i was able to buy it.

Very fun game. If you're into rockets and space, you'll love this game. Even when your creations fail it's still fun and entertaining.

Difficult to learn, even more difficult to master, and damn good fun.

Although Difficult, the time spent getting to know the game is worth it. You won't find a space game like this anywhere else. It is very polished.

I've always been a fan of KSP. I own it on the XBOX and have played 100's of hours on it. I recently switched to a PC and saw the bundle on sale for KSP. Of course I bought it. Now I can play the same game I REALLY ENJOYED on the XBOX and enjoy it even more on my PC. (So many MODS on PC) I've seen what happened with KSP2 and it's really a shame. BUT the good thing is we have KSP 1 and with so many MODS to choose from for graphics etc it was an OBVIOUS choice what to buy. I'll probably never not play this game lol. KSP 1 IS KING. AMAZING GAME. If you don't own this game you should add it to your library. <3 KSP

Oh and BIG shout out to the KSP community! KSP wouldn't be what it is today without you. THANK YOU

1: buy the game
2: no idea what am doing
3: replay the tutorials for the 10th time
4: still no idea what am doing
10/10 game

Only says I've played for 18 minutes, but I've spent a lot more time on modded installs that don't track. Even if I did only play for 18 minutes, I'd still recommend this game. Whole lot of fun, and mods aren't even necessary to enjoy it.

- Build a rocket
- Put a literal bean person in it
- Explode
- Repeat
10/10 would recommend to anyone who likes space and rockets

Fire and fun game especially with mods (that's where it starts to get even more fun then it already was)
