An open letter on the Witcher website from CD Projekt RED co-founder Marcin Iwiński reveals that The Witcher 3: Wild Hunt sold more than four million copies in the first two weeks of the release of the RPG sequel. On a semi-related note, this video helps explain Gwent, the collectible card game contained within The Witcher 3. Here's word on the sales milestone:

May 19th was a crucial date for all of us here at CD PROJEKT RED -- we released The Witcher 3: Wild Hunt, our open world role-playing game that we had been hard at work on for over 3 years. Since day one, you have given us tons of positive feedback and support -- the sheer volume of emails we’ve gotten since launch simply congratulating us for our efforts is both epic and heartwarming, and I wish every developer comes to have such a fantastic community. In terms of media reception, we’re really humbled by the scores the game has received all around the world. With an average of 90+ on every platform, Wild Hunt is our dream coming true.

I’d also like to take this opportunity to thank the four million gamers worldwide who bought The Witcher 3: Wild Hunt in the first two weeks from launch. Four million RPG fans spending their hard-earned money on our game is a sign that we did something right, and you can be sure that we’ll harness all that positive energy and make the upcoming expansions worthy of the grand adventure that you’re telling us Wild Hunt already is! Until then, keep on enjoying Wild Hunt, do not forget to grab your weekly set of free DLCs, and stay tuned for constant updates and enhancement to the game we are continuously working on.
