Blades of Avernum is another quality role-playing game from the makers of Geneforge 2, which was also reviewed here in January. But it is not just a game. It's an entire role playing system! While it comes with four adventures that range in difficulty from easy to hard, games entirely of themselves, you can also download more adventures from Spiderweb Software's site. You can even make your own adventures with the Blades of Avernum editor, which is pretty powerful, well documented, and amazingly easy to use.
