Love having all my party members twiddling their thumbs defending and healing while one guy fails his steal rolls 10 times in a row
I extra love it if the steal move deals damage so you have to also worry about the target dying from too many failed attempts
I double extra love it when it's a boss battle when on top of everything else the story momentum just grinds to a halt while you fuck with a stupid RNG for 5 minutes
I mean, the protagonist is locked into a pseudo-class of thief, he is part of a troupe of thieves, and thieving is a motif throughout the game with you visiting the thieves' hideout, going to a city of thieves, the kidnapping of royalty and fighting against others to protect your loot etc. etc.
From my perspective you're underselling how thieving is central to the FF9 story by saying that it's simply one command in a battle menu.
