As far as I'm concerned, the junction system was the pefect excuse to replay the game. Without guides or help, you're likely to completely fail at manipulating it until about halfway through the game, which will encourage you to go back and do it again, doing it right the second time.
All I know is that I once was able to give 3 characters 9999 health and 255 (or whatever the highest available is) strength by the end of the first disc.
I was unable to recreate that my most recent time through, however. I am disappoint.
Either way, my FF games are ranked like this:
1 - Final Fantasy VI - 100% - Ranked #1 all time, #1 FF game
2 - Tie between VII, X, and XII - 97% - Ranked #6 of all time togethery, #2 tier FF games
3 - Tie between VIII and IX - 96% - Ranked #11 of all time together, #3 tier FF games
4 - Final Fantasy Tactics Series (Advance as well)- 90% - Ranked just outside my top 25 list, #4 tier FF game
5 - Final Fantasy I - 85% - Ranked somewhere between 26-50 on my all time list, #5 tier FF game
6 - Final Fantasy X-2 - 83% - Ranked somewhere outside my top 50
I didn't much care for II or III, Never played IV or V, (though I will be remedying that ASAP, thank you FFIV Collection on PSP and FFV remake on PSN!). Crystal Cronicles doesn't register, and 11/14 doesn't count. I loves me some FF games, no doubty there! every game from VI-XII is on my top 12 games of all time (barring XI), so you know I love FF!
Sorry, I'm rambling, I'll stop.
