I've decided this will be my next challenge. I started earlier tonight and I'm done for the night. So far I just got done with the SeeD Party after the Dollet mission.

As usual, I'll keep anyone interested updated on my progress. I am thinking about making this a high stat challenge after I reach the end of the game at starting levels, although I haven't decided yet. As of now my goal is to simply reach Ultimecia and beat her without ever gaining a single level.

Wish me luck.
