Steam is a double-edged sword. I have access to 15 year old games on all of my computers today. This would be a challenge for a game distributed on a disk with DRM. However, my 1000+ USD library could vanish with one internet outage, if steam goes bankrupt, if steam makes legal missteps, if steam decides they don't like me, etc.

I de-googled to avoid being at the mercy of a for-profit company for more important identity-related matters, but it'd be a sad day if I ever lost access to the archive of games.
