In a previous timeline, this has led to me going on ebay to find CDs of a long lost game (EarthSiege 2), which I promptly uploaded to the Internet Archive as the one distributed by the current license-holder at the time had an older, unstable version with bugs and, more importantly, no audio and my own original copy got damaged to hell and beyond...
Don't get me wrong, as mentioned, I use Steam and like Steam/Valve, but that move is a bit shitty regardless.
