XYCat: Why did it disappear from steam? Or perhaps why would it disappear from here?
Who knows for sure, but I guess it could be for similar reasons as why Space Rangers games disappeared, or many others.
GOG's/Codemasters' little ploy eventually worked, they just managed to lure me into buying some of the Codemasters games from GOG (without discount): Second Sight, Soldiers, I.G.I. 2 (debatable) and Perimeter. I was supposed to get those four games at some point anyway. $40... I use much more for gasoline on my car every week! And at least the games are guaranteed and supported DRM-free.
Skipped: 1nsane I already have on retail, and I don't care about Sensible Soccer 200x.
