So I was thinking as playing around that the part i really enjoy from ff games is missing.
So I have a suggestion for this to be in the game as a minigame in the open world.

The game would be target/marks to steal from, the mini game im suggestion would have no fighting, if you enter or get seen you automatically lose. The game would require taking out lights, stealthing around boxs,crates in order to steal items,gear.

I believe this would not only be extremely fun but also give (theif fans) something they can enjoy. This could also help the open world by small group of two of three people for bigger targets and higher risk.
