Great game, one of a few with Eastern Slavic setting (the only one on GOG up to my knowledge). If you are interested in unique cultural experience, then try it, although it will be better in Russian :) After all, we haw only a few kinds of fantasy games/worlds - Western Europe-like, Scandinavia, Arabic or Far East. There are exceptions from Check or Polish developers with unique Western Slavic flavor. But they are all very rare and long between. Graphic is nice, although of course outdated and English translation replaced much of the uniqueness of game's cultural background (knyaz became konung and etc.)
