StarbaseSim

What is this?

This is a physics sandbox where you can play around with Starbase (在新标签页中打开) 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 not much explanations yet in the game. So you either have to know already what you are doing or find out by clicking around ;)
For more info, go to the Itch site (在新标签页中打开) or join the Discord (在新标签页中打开).

Demo?

Yes! -> https://ashtorak.itch.io/starbase-simulator (在新标签页中打开)

There will always be an older version of the game on Itch, just without multiplayer, that is free to download and try.
Here on the store you get early access to the newest version of StarbaseSim with multiplayer, and of course, you support the development of the game.

What's the plan?

The basic idea with this project is to closely follow and recreate the developments of the real Starbase.
Read the Itch page (在新标签页中打开) for more details. 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.
