I've been playing the Avernum series since it was the Black Crystalis saga. There is a large amount of customization to every party, from traits to spells and even races. The traits themselves are interesting enough, almost like miniature backstories. It's really the story that will get you. In every instance, you start out as a small group of adventures working for the military. From there the world slowly draws you in, from the gruff soldiers, to dragons with hearts of gold. You'll travel the cave like world to find treasure, adventure and fame. The combat and GUI can be a little sticky, but it takes only about 5 minutes to get used to it. Honestly, if you need to kill some time, are bored with your standard rpg's, or would like a game with a unique interface, this is what your looking for.
