StarbaseSim

Small UPDATE 2026-02-27: Trajectory Prediction

Important info before you buy the early access version: Development is progressing on a very slow pace currently and there will probably only be small, infrequent updates going forward.

What is this?

This is a physics sandbox where you can play around with Starbase devices. This is not a flight sim. There are some basic flying mechanics, but they are mainly intended to be able to catch the rockets with the chop sticks.
Also, there is no tutorial and just some explanations yet in the game. So it would be better, if you know already a bit about what you are doing or you find out by clicking around ;)

What's the plan?

The basic idea with this project is to closely follow and recreate the developments of the real Starbase.
This will stay in early access for a long time probably. There is lots of stuff to add and things to fix.

What's the catch?

SpaceX tries to catch the first and second stage with the same tower where the rocket lifts off in order to rapidly reuse it, like an airplane, which would reduce costs to launch something to space enormously.
Or are you asking about the game? In that case it's simple, you buy it once, you get everything, all features and all future updates, and of course, you can always use single-player offline. Price will go up though in the future, so better get it now.
