Worth buying? What 300 Steam reviews say.

Overwhelmingly Positive2015

US Steam price, checked 5 h ago

The verdict

A deep, good-looking physics sandbox for smashing planets, making black holes and building star systems. Skip it if you want goals, have a weak PC, or bought it for VR.

Great for

Space fans who like what-if experiments, blowing up planets and building their own star systems

Main risk

It has no goals, so many players get bored within hours, and weaker PCs struggle.

What players love

“You can literally just make your own solar system, throw planets around, change their atmospheres, mess with gravity, make stars, create black holes, smash planets together”

“There is no actual gameplay. No objectives. Just sliders, simulations, and ambient music that should come with a warning.”
