I do. My rule is that none of my chars can ever be KO'ed. I can't ever lose at the card games, blitzball, or sphere break. No cheat codes whatsoever. That includes glitches like the regen trick in ff7. Oh yeah, and no walkthroughs the first time i go at the game. I'm allowed after I finish it to see what I missed. Ive finished VII, VIII, X and Kingdom Hearts like this. I lost X-2, and I'm playing IX currently. If any1 has any rules they go by, tell me pls. I don't like to feel like a freak.
