Prices
Each in the currency that store quoted — not converted: the gap between two rows is the publisher's pricing, not an exchange rate.
Discounts
Every price cut of more than 20% we have observed, in each market that quoted one, with this game's chart position on either side of it. These are episodes, not a model: a sale is one event, and one event cannot tell you what the next one will do.

nothing, its great
I made a ship that was capable on going to the moon but I accidently stranded a kerbal orbiting the moon. I then did a rescue mission to save that kerbal in which that kerbal got stuck in the suns orbit. I then did a third mission to save them in which it would eventually line up and I could maybe save the first kerbal so I waited about 300 years and at the perfect moment I missed it and got him stranded out their too.

This and every other Pro feature is free until October 20, 2026. A free account is all it takes.
Every market we collect.
Reviews, worldwide (the counter carries no country): 37.43/day in the week to Jul 30 → 45.14/day in the week after.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 22 chart moves that followed a price cut of more than 20% went a median of 9 places towards #1, and the 2,513 moves with no price cut behind them went 2 away. One store, one chart, one country — it is the only place we have enough observations to say even that.
Prices outside the United States have been collected since 6 August 2026 and chart positions since 19 July 2026, so a cut older than that has no market to compare and a market that joined later has no history yet. Nothing here is converted between currencies.

Kerbal space program saved my grandma
i still havent gotten into orbit, will get there ONE WAY OR ANOTHER
One of My All-Time Favourite Games I have sunk more hours into Kerbal Space Program than I care to admit. Most of those hours have probably been spent crashing rockets into the Moon, launching them into the great burning ball in the sky, or spectacularly failing in ways I absolutely did not plan. This game has been installed on every computer I've owned over the years, and I still keep coming back to it. You can play through the career mode and actually work your way through the game, or jump straight into sandbox mode and build whatever ridiculous contraption you can think of before launching it into space and watching everything go horribly wrong. There is so much freedom, so much creativity, and so many ways to completely screw up a perfectly good rocket. I absolutely love this game. It's one of those games I'll probably keep playing for years to come.

Great game. End
1. Get KSP. 2. Spend 18 hours a day for three days straight figuring out how to land on the Mun. 3. Celebrate Jeb's 47th anniversary orbiting Kerbin without hope. 10/10 Would Ruin my Sleep Schedule again.
