Nothing in either version actually mentions anything about mandating a login to their platform either. So my argument with the EULA in specific is moot.

But yes, a diff on BOTH EULA's on the steam page show at least no change in the past couple of months. But that doesn't prove anything about when this specific user purchased the game. A change could have been made, and they would have only agreed to that version. That's the point though, that's something you have to explicitly look out for.
