I’m playing through the bonus Adventures included with The Witcher. Read about the earlier Adventures, along with an introduction to the game, here. Also remember that you can click on images to view larger versions.
After The Price of Neutrality, the next Adventure on the list is Side Effects, also by original developers CD Projekt RED. It was released in 2008 along with the Enhanced Edition of the base game. Like The Price of Neutrality, Side Effects is fully voiced (and again, please use the original Polish voices) and is on par with the main game in terms of production quality. Unlike The Price of Neutrality, Side Effects is not focused on narrative, instead reveling in the pure mechanics of the game.
