How many GB is StarbaseSim?

2 GB

That is less than the typical Simulator game, which needs about 4 GB.

Leave at least 8 GB free: games need headroom to unpack updates.

The figure is the storage Steam lists as required for this game, not a measured download.

Operate the Starship space launch system and learn how to catch a rocket to understand what it takes to colonize Mars in this ever-evolving simulation of SpaceX Starbase Texas. 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.
