As of 10-24-2001, this game has been renamed to RanziorSigma. It is in the process of being updated, and hopefully to the third chapter/saga/enemy, Niofalfe. Go to RanziorSigma.
"Sigma isn't a bad RPG, then again it's not a good RPG either. If the Xi battle is made easier then the game would be a lot more fun. Download this game if you have some spare time."
