June 2025

- Bought the game - Built rocket - Rocket is success, but the pod blew up on contact with the ground - Launch mission to the North Pole with all my Kerbals in it. - Plane engines blow up on arrival. - Kerbals are stranded there. - I sent 10 planes to help them, but each and every one blew up or ran out of fuel. - After 7+ hours of sending rescue mission to help them, FINALLY one of the planes make it to them and rescue a survivor of one of the failed rescue missions on the way there. -Complete the main rescue mission and pick up all of the Kerbans. -There are still 2 other Kerbans out there in the Tundra because I'm too lazy to rescue them. 10/10 game, would kill 11 Kerbans whilst on a rescue mission again.

playing this game is by far the best way to intuitively understand orbital mechanics. it also was a big inspiration for me personally. I went to work in the aerospace industry partly because of this game, and have worked on 4 satellites and a launch vehicle professionally.

Best space sim game ever. Remember to watch Scott Manly and may the delta v be with you

More than ever, this game is relevant. You probably heard of the disaster that KSP 2 ended up being, but if you did not, know that this first opus, this KSP is the one you're looking for if you want to explore space while using realistic physics and methods. As a base game, it is solid on its own but, it does have a few shortcomings and bugs. This is why, while I do not recommend modding the game from the get go in order to understand what you are actually modifying, it needs to be said that the modding community for this game is still going strong almost a decade after the final release. They have come up with their own mod manager (called CKAN) and most mods are compatible with this final release of the game - we're talking abandonned mods by their original creator being updated by members of the modding community for the final release. You can expect more content, more game mechanics, updated graphics and visuals, textures etc... Most of what you would need it there in the game. Even multiplayer support - although this one is capricious so no promise on that front. What I can promise though, is that mods on CKAN are free. Speaking of pricing, 70 bucks is expensive - considering the expansions which are mandatory imo, and even with modding in mind. Just know it goes on sale regularly and can drop to below 40 bucks, which is a bargain. So maybe wait to get it, but know it will be worth your time and money.

Dec. 2024

better than KSP2 by a long shot. Unbelievably moddable. May require a NASA PC if you add too many parts. Kill little green frogs in a multitude of ways. Commit genocide under the cover of a space program. 10/10 would recommend

SimpleRockets I am excited to release my first game on Steam! SimpleRockets was released in 2013 for mobile and I've put a ton of work into it to get it ready for PC and Mac. It was inspired by KSP, and it offers a simpler 2D experience for building rockets and exploring space with realistic orbital mechanics.
