Some people are pathologically incapable of imagining the consequences of things that happen around them.
Or, you know, we just don't spend our lives worrying about worst-case scenarios.
Here is my position. I will not buy this game in any format that requires connecting to Steam.
If there is a Steam-free boxed version that can offer me that, I will gladly buy it. It sounds like D:OS is the kind of game that would justify acquiring collector's edition.
If there is no such boxed version, I will wait for GOG.
See, that's all you needed to say.
