The gothic castle idea was pretty good. Shurik (Paulus) posted some hand-drawn sketches and, as far as I remember, there was a layout for the levels. The idea remained just an idea because Paulus is one of the founders of STORM. That's why he abandoned his idea and started working on the development of a water city. Unfortunately, he left the team a long time ago and doesn't appear on ICQ at all (maybe he changed it). In general, contact with him has been lost.
