Gwent returns in The Witcher 4, according to CD Projekt's heavy hints
Quick, the world is in peril, your adopted daughter is under threat, and nearby villagers are being terrorised by monsters. What do you do? Oh, you're sitting down at a cosy table in the local tavern. You're playing a card game with a dude called "Aldert". The wind outside is howling, and so are the nightwraiths, but you're just sitting there. Playing another "cow" card. Okay.
Guess you'll be happy to learn that the Witcher 4 developers have more or less confirmed that Gwent will be making a return in the recently trailered Ciri-led sequel.
