That is nice to know! I have played The Dark Eye videogames from Daedalic Entertainment and loved them (Memoria is still one of my favorite games), but I didn't know there was a RPG system behind them.

On the topic, I am actually also looking for a crunchy, classless, and gridless fantasy RPG system. I think will go with Burning Wheel, since it has a very good balance between combat and social interaction, and is focused on character development.
