The world of The Witcher 3: Wild Hunt is dark and full of terrors (preview)

You know, when you think about it, The Witcher video game series shares some similarities with the hit HBO TV show Game of Thrones. Both are based on works by popular fantasy authors. Both tell tales of characters that are neither completely good nor completely evil. Both are set in harsh fictional medieval worlds populated with mythical creatures, scheming nobles, and the occasional brother-sister incest.
