No FRUA?
While some modules for FRUA stand among the best CRPGs I've ever played, I can't vote for FRUA itself because it only comes with one built-in game. That game, "Heirs to Skull Crag" is the worst attempt at a Gold-Box game ever made, and gets nearly everything wrong. So, no FRUA.
Did you vote for it?
