As soon as I saw it on Steam I forked out the money for it and promptly installed it. So far I have only spent about 2 hours in this game doing important scientific experiments like what would happen if the Earth suddenly got the mass of the our sun and other important things.
And I loved every minute of it. Thank you!
I did try to see what would happen if a persistent black hole suddenly opened up near Geneva and France
but I couldn't figure out how do that that.
But again.. loved fiddling around with this lovely piece of software.
