After a few years of sharing around my Fate Core principles post, I have had further conversations with people about it and developed some more ideas about Fate (broadly, not just Fate Core) that explain a lot of the issues that people report to me that they have with Fate. If you've struggled with it, especially if you were around for the Dresden RPG or Spirit of the Century, give it a look, hope it helps.
Here are the two things I want to try to get at:
1. People love Aspects too much. They shouldn't. Aspects are great but when you love one too much it can get in the way of what their actual function is.
2. If you're feeling both "I shouldn't get Fate points just for doing something I would or should do anyway" and "I'm always running out of Fate points", someone at the table is badly miscalibrated about what the action of the game is.
