The top 100 list has already been posted, but I thought this article makes some interesting observations on the list.
Overall the variety of games and experiences on that list really show how versatile the deck is, and that people can still have a great time with games that aren’t a perfect experience on the deck.
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.
