I know there is a thread about this somewhere, but me and the search function don't get along (aka it hates me)
So
Ideas
1. Less Aspects
7 is too darn many.
So lets keep
High Concept and the Trouble. They work pretty well, and they are simple to use and simple to understand.
Then two more that flesh out your character
The last one, this is the one I know I will get the most flak about which leads me to
It's too many to keep track of as a GM (3-5 players each with 7 Aspects, plus any scene aspects, stick aspects, city aspects, theme aspects, and the NPCS aspects is too many) Also after 3-4 they start to lose their "bite"
2. Drop the Guest Star Aspects
Instead of complicating character creation with somehow tying everyone to everyone else. Make your last Aspect tie into the game you are playing. So tie it to the City Aspect, or City Threat.
Example You are playing in a game where you are the Justice League and you are fighting Darksied. You play Batman, and the other two players are Aquaman and Plastic man
Batman
High Concept: Millionaire Playboy who dresses like a Bat and fights crime (or something along those lines)
Trouble: My Parents are Dead
Aspect: Where does he get those wonderful toys
Aspect: I'm the God D*mn Batman
Campaign Aspect: A Man among Gods
IF we did it the Dresden Files current way I would have to tie an Aspect to Plastic Man, and another to Aquaman. Meaning my Plastic man Aspect would be as important as the one that deals with my parents death. Thats nonsense.
3. Mental, Physical, and Social? Social and Mental need to be smashed together. Social Stresses could be better used as Sticky Aspects placed on Characters "Destroyer of the Red Court" or "That rude guy"
4. I really like contests in the Fate Core, and would love for them to be used in a new Dresden game. I also would like to steal, I mean pay homage, to Diasporas Social Conflict map. As is in the game, Social Conflict between characters means jacking them up. Which is nonsense. If I disagree with my friend about what movie to see it doesn't involve my scaring them for life so I can watch Kangaroo Jack (which is already scaring for life)
5. Magic. Um...to say the Magic system can get complicated, is well, um yeah. So feel free to add what you want to see in magic here.
6. Stress boxes. I'm mixed on this. I like that you can be taken out easily. I just don't like that if I have open stress boxes you can still be taken out. Hmmm.. Maybe it's fine the way it is.
7. Skill problems.
-Oh you took Performance at a +5, because you are a great actor. Now you're going to tell this guy a lie, roll me deceit. Why couldn't I roll Performance instead? Anyone? Maybe make some sort of buy in when it comes to skills? As I see it now, not all skills are not created equal.
8. Don't make me roll if it's not interesting.
Anyway, thats my ramble, I'm sure I can come up with more
