One thing I never really liked was how the bosses horded all the useful steals and the regular monsters had generic crap -- that really makes stealing pointless a lot of the time, 'less you're powering-up Thievery, trying to get ethers to sell, etc. There was a fun enjoyment in finding rare baddies to rob, and FFIX kinda went bust on that end. But it's really a small grievance in the face of FFIX's well-roundedness.

I guess the only real exciting steal I've ever had was getting Hilgigars' Fairy Flute, which, at this point, is a notoriously difficult catch -- some people play for hours just getting it. What's worse, the item actually sucks and is soon outclassed...haha.
