IGN: S.T.A.L.K.E.R: Clear Sky Developer Diary #4

There's a whole bunch of charismatic NPCs awaiting the player in Clear Sky. Apart from the gang that hangs around with Strelok, anyone who's played the original game will also be familiar with Sidorovich the trader, who joins a handful of other characters from Shadows of Chernobyl. They'll be plenty of new characters too, and on that note GSC wanted to bring something fresh to the game - they didn't just want to make characters that were similar, visually and behaviour-wise, to previous characters. Admittedly, thinking up dozens of original characters is a challenging task, even for a group of experienced writers, which is why they called upon the help of their players - people who loved the first game and knew exactly what the world is about.
