I found a place that explains the number setup, but forgot where.

Back on topic, the games I feel like starting over the most are Final Fantasy VII, Final Fantasy Tactics, and Final Fantasy X. Final Fantasy X-2 was pretty fun as well (the more "active" Active Time Battle system was one of my favorite parts ). The game with the most crap to do would definitely be Final Fantasy IX, but I found that game boring (even more so than Final Fantasy VIII). All the games I listed are fun to play, I just find FF8 and FF9 boring (FF8 for it's terrible junction system, and FF9 for all the chatter).
