Ha, so I beat FF1 with all 6 players on solo, thief was absolutely sick in the hardness aspect but it worked.

Is a very cool game, I'm enjoying it a lot, looks like a lot of detail put into it.... good quality!

I have now beaten with solo parties: 1 Fighter, 1 Black Belt, 1 Red Mage, 1 Black Mage

soon I will do the solo white mage... but thieves suck.... don't know if that ones possible
