I'm on a distribution that doesn't support steam - at least not without a lot of complex and incredibly repetitious workarounds. I only purchase DRM-free games, and they work out-of-the-box here - I've tested by downloading and copying them over from a virtual machine via steam.
In other words, steam is a completely unnecessary, tedious, and painful version-control middleman.
Can I get the latest versions of my purchased games without having steam installed?
