I agree on everything the posters before me have said, and really recommend this game to you, if you feel you like it (and I can see why not everyone would) You can really lose yourself in the background, as the developers made a very good job of keeping the setting detailed, realistic (as far as I can say, and I'm by no means an expert, Aventurien, the main continent, is a pretty realistic medieval realm, only with amgic and gods that are actually represented on earth, or Dere)
But! You may have noticed that so far, every poster in this thread is of German origin, and the main reason for this is that it is a German game. While I believe there is a translation of the basic rules, which are all you NEED to play, you are really missing something if you have no access to the other books that detail new professions, magics and regions.
Still, I would recommend it if you and your friends are up for something different.
