Galaxy4D : New Multiplayer Space Sim

Greetings people of earth,
We are officially announcing our new game and would like to have your opinion !

It's a multiplayer space simulator featuring accurate space physics including General relativity and orbit simulation with real-life gravity maths.

The concept is an open-world full-scale Galaxy where you can walk on planets, survive in a hostile environment, find resources, build a spaceship and fly to another planet seamlessly, no loading screen !

The fun part is the actual challenge of managing the spaceship's systems (futuristic technologies) in a very realistic way , alone or in a co-operative way with your friends.
