But it wasn’t worthless to Epic, who potentially sold it, active address or not. It doesn’t really matter what happens with it further down the chain after that sale. The point is that simply signing up for an account, even with fake credentials, does give Epic something. Not a lot, but something.
Just to make sure it’s clear: not being Deck Verified doesn’t mean it won’t run on the Deck or on Linux in general. It means Valve has not hit their testing threshold for the title to mark it as verified or unsupported.
More specifically, it means Valve cannot guarantee a) the game will run (though anecdotally, I’ve had most if not all unverified games I tried work without issue), b) that the text is large enough to be readable on the Deck, or c) that the controls are usable (=you might have to just use the configurator yourself).
I think a danger Valve has introduced with the verification system is people thinking that not verified == no worky.
