You may also consider the Fireborn GM book as a PDF. It is $5 IIRC and has tons of excellent stuff for a Dresden type game. Most of it is systemless too.

We are probably going to start the same process for London in a few weeks. Happy to share.

We have done one brainstorm so far and have the following questions/thoughts:

London has a lot of greens pace which suggests sidhe.
Why is London not a Red Court or White Council stronghold?
London is old
London has its own dragon
London has its own giants
the tube is ideal for something. Ghoul clans?
 

Use a .50 BMG round. Or a shotgun loaded with steel shot, if you are hunting Fae.

Running a business of taking hunters into never Never to hunt big game with iron shot! And I wonder just how long that will last before one of the queens comes down on him like a ton of bricks!

I am looking at making a wizard who is a blacksmith/artisan. Using traditional crafts to make jewellery etc and also work as a farrier.

I interested in how you have fitted your wizards into the real world whilst working around hexing? How do they make a living?

First, I agree with what has been said before, you need to find out the OOC reasoning. Particularly if it was an intentional throwing of the game/character.

Assuming the worst case that the player was throwing the game/character.... Well that comes down to group dynamics and people.

Assuming the best case scenario of the player not getting it but wanting to continue.... You could do all sorts of things until he fixes it:

a RP encounter with Titania resulting in an extreme social consequence
a -1 refresh 'power' kind of like the warlock one so the character is on 0 refresh
set a threshold on fairie, not only does it require a skill roll to pass over but he has to leave a lot of his power behind

Are you kidding? Murphy usually has a vest on. Check Proven Guilty for an example. Plus Michael's plate/kevlar combo, Kincaid's tendency towards armor, John Marcone's armor in every fight he goes into prepared...

And remember Murphy's armour was compelled when trying to crawl under a laser beam.

FATE tends to work on the "what's reasonable?" for equipment. I tend to look towards aspects and skills. Is it reasonable for a person with those aspects or skills to have that thing? Is it good for the story? Why is it a problem if I say ok? Why is it good if I say ok?

With body armour you have to think about options. Police riot gear is bulky and hard to hide, kevlar under vests are less effective and tend to need more justification (Aspect is your friend here). They also are not very good against blades/claws you need the ceramic plates for that so will only help against guns anyway.

So if your team is going out planning for trouble then of course they will kit up... Harry takes his gun. If they are surprised where they were not expecting a fight then having the armour would require a declaration and probably a Fate point. Kevlar pyjamas are quite rare.

Subtle spirit is the real of light and shadow and other subtle manipulations, just avoid the force blast, lifting and shields. I am going earth, air and subtle spirit for my caster.

Thoughts...
Create light
Dazzle
Blur (defence option)
Veils (of course)
Lockpicks
Strobe lights
Block light (darkness spell)
caress (someone just touched me aspect... good in the dark or to get someone slapped)

I would suggest looking at starblazers or Diaspora. Both have systems for statting spaceships and other things.

Its about scale. Once something gets out of scale it more or less becomes unable to easily interact with something of another scale.

With vehicles etc you need different skills generally the things you roll against. Stunts then add the specials and aspects well aspects.

Starship Enterprise
Scale: Starships

Skills
Phasers good
torpeadoes Great
Maneouvre Fair
Shields Good

Stunts
Transporters
Suttlecraft
Warp drive

Aspects
The engines cana take it captian
Flagship of the fleet
etc
