Eisenstern is a novel RPG game built on the Sauerbraten engine. We are currently in the preproduction phase. You can follow (or even participate in) Eisenstern's development in Cube & Sauerbraten forums. Sofar the development of the game has piggybacked on the Sauerbraten / Cube 2 FPS game, it is expected that soon the two projects will diverge and seperate downloads will be available. For now, to see early versions of the RPG worlds we are building, simply have a look at the ones included with the FPS game. Along these lines, the authors are currently the same as Sauerbraten project, see the documentation for that. The game design for the RPG is still in flux, and will be throughout its development. Some random notes on the direction we are going are here. Wouter's homepage.
