The universe sandbox game

[isee]

Available on steam for 6 quid.
got it yesterday haven't had time to play about too much but it when changing the earth's mass to that of the sun, mercury and venus got ejected from the solar system. If you are into that kind of thing, then I can highly recommend this "game" it's amazing to see how gravity and speed of light affects us and our system.
The simulation goes further than that. you can create your own systems and even galaxies
