The Witcher

In 1996 and 1997 a Witcher video game was being developed by Metropolis Software in Poland, but it was cancelled. The game's director was Adrian Chmielarz, former People Can Fly co-owner and creative director, who coined the translation ``The Witcher'' during its development. According to Chmielarz, the game would have been a 3D action-adventure game with role-playing elements such as moral choices and experience points. In 2007, Polish video-game developer CD Projekt Red released The Witcher, a role-playing game based on Sapkowski's saga. The game was released in Europe on October 26 and in the US on October 30 for Windows and OS X. It was well-publicized and, although it was the developer's first game, it received critical praise in Europe and North America. The Witcher was published in Poland by CD Projekt and worldwide by Atari. A console version, The Witcher: Rise of the White Wolf with the same story and a different engine and combat system, was scheduled for release in fall 2009 but was cancelled that spring.
