There seems to be some very interesting text in tooltip_ui_strings.mes pertaining to "The Arena" as well as plenty of other interesting features which didn't seem to make it into the game. Here's the details: From the looks of things, Troika wanted to set up an Arena for your party to battle a random group of monsters. A terrific idea, really. I wonder how difficult it would be for us to do something like that. The arena map still exists, I believe.
