The Witcher is an RPG about the adventures of Geralt, a professional monster slayer, and was developed by Warsaw, Poland-based CD Projekt RED. The game is based on a new version of the BioWare Aurora Engine, titled Aurora 2007. The story is set in a world created in the books of Andrzej Sapkowski and sold all over the world. The game has already managed to garner worldwide success, having sold over 600,000 copies.

The Witcher Enhanced Edition not only means changes in the game's mechanics or better graphics, however. There's also an included mod editor called D'jinni that allows players to create or modify their own adventures in the world of The Witcher, as well as two completely new adventures created by CD Projekt RED. The first adventure, entitled “The Price of Neutrality,” tells the story of Geralt coming back to Kaer Morhen and finding a mysterious camp near the stronghold (3 new quests), while the second one focuses on Geralt’s close friend, Dandelion, and his troubles in Vizima City (5 quests).
