Not using it this way, but wanting to: a friend of mine is working on a TTRPG. He has items, powers, other things to track - and right now it's in a mess of a Word document.

It would be so much better if he could store these things in SQL - for non developers, they often use Excel, when a SQL DB is the correct solution, just because they can't figure out SQL at all. A visual editor/manager is perfect for them - create a table with columns, enter data, later integrate with other tools that can pull it out.
