Valve has now certified 5,000 games as Steam Deck compatible

engadget.com:

Valve wants to help Steam Deck owners and folks interested in picking up the device easily find out what games can actually run on it. Through its verification program, it hopes to let people see at a glance whether a game is compatible. Although it will be a long process to test every game (assuming it goes that far), Valve just passed an important milestone. The company has now certified 5,000 games as Verified or Playable on Steam Deck.

If Valve slaps a Verified label on a game, the Steam Deck should be able to handle it with few, if any, issues. Should Valve determine that a title is Playable, it will work, but there might be a few caveats or niggling issues. On the other hand, Valve has listed nearly 2,000 games as Unsupported, according to SteamDB, meaning they probably (or definitely) won't work on Steam Deck. 

Those numbers suggest Valve has tested at least 7,000 Steam games on the system. There's a long way to go to check all of them, though, since there are well north of 50,000 titles on the platform. It's worth noting that many of the games currently labeled as Unknown work just fine on Steam Deck, even without a Verified or Playable sticker.

Oh hey, another big milestone - we just passed 5,000 tested Verified and Playable titles on Steam Deck! Plenty more to go (so many games on Steam), but just wanted to take a moment to celebrate!
