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.
