It was a good start at Steam I think - about 1200 people playing in the peak:http://steamcharts.com/app/265630
Before it was released it was pretty dead, even more than SG. And, btw, this is not the full game like it was outside Steam. There're more modes and many things changed but it was removed for various reasons during preparation for Steam. But it's actively developed currently and more stuff will come to the game.
