With S.T.A.L.K.E.R.: Shadow of Chernobyl, developer GSC GameWorld proved that you can make an innovative, specs-testing FPS with a small team - but it will probably take you the best part of a decade to get it finished.
Now hard at work on a prequel, S.T.A.L.K.E.R.: Clear Sky, which is due out in August, it's hoping not only to trim the production cycle, but also deliver a game that truly lives up to their initial concept. Following their preview session, Eurogamer caught up with Oleg Yavorsky, the developer's PR director, to discuss unusual inspirations, the danger of revolutionary technology, and the trouble with making games for "non-intellectuals".
