It took 
The Witcher 3: Wild Hunt just two weeks to sell four million copies, according to developer CD Projekt Red co-founder Marcin Iwiński.
 "With an average of 90+ on every platform, Wild Hunt is our dream coming true," Iwiński wrote in an open letter on the game's official website. "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!"
 Pre-order sales for 
The Witcher 3 topped 1 million by May 11, eight days before the game's release.
 The Witcher 2: Assassins of Kings took about three months to hit 940,000 in sales.

Dear Gamers,
 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.
 Dandelion once said to Geralt that the world is changing, the sun is setting, and vodka's running out -- go, play, and have fun!
All the best,
 Marcin Iwiński
