For Mac, it's out. For Windows, end of March. After Avernum 2 there are two other games we know about. It is a HUGE game, with a really interactive world. If you don't do anything, the monsters will tear the world apart.
Some people move from town to town.
The interface and game system will be similar, though. I have a hard time abaondonign something that my users have generally been very happy with. It is a fantasy role-playing game with science fiction elements. It is real time when moving around, and turn-based in combat. In the game you are captured by someone trying to steal your powers.
