Leonid sent me some screenshots of an Irrlicht based game named 'Fear & Loathing in Leningrad'. It is not commercial and the project is now frozen. There are 14 locations & 8 characters in the game. It looks like this:
In short, the story of the game is: "The main hero of game, addict Slavon eats narcotic porridge and gets transfered into a parallel universe."
I've not much information about the game, but it looks very interesting, IMO.
