I'd say if I have one big complaint about Steam, it's that it's update control needs work. I don't know if it's intentional or not but rolling back to an old version is...impossible? I'm vaguely aware there is an option to maintain the version you already have but I believe it's quite buried.

I've had updates completely change game balance, making character load outs I'd grinded up not work the way they did before. I've also had new linux versions break compatibility. This is understandable in multiplayer games, but I was playing these games single player.
