I must say, I was blown away back when I tried Universe Sandbox over a year ago. I'm even more blown away, now, to see the program on Steam and receiving so much attention (and an update).
How big is the Universal Sandbox team--and can we expect a sequel or further patches?
Often times, I've seen brilliant little projects like this stifled for lack of resources, money, time, and too few programmers with too large of a project.
Anywho, I'm incredibly excited to see this program receiving more attention!
