Decks, the kind you create with playing cards, hasn't yet had a Fest on Steam yet. Don't worry though, because Valve is righting that wrong when the Steam Deckbuilders Fest arrives on March 25 at 10AM PT and ends on April 1 also at 10AM PT.
While this Deckbuilders Fest is not specifically for Steam Deck titles, I'm sure many of the games available during the course of the Fest will be playable on your Steam Deck.
Woodworkers, skateboarders, DJs, sailors, cassette tape enjoyers, and those who like to observe will all be left out in the cold during this Steam Deckbuilders Fest. I'm sure your time to shine with a Steam Fest will come one day.
