One choice is physical book verse PDF (the PDF is much cheaper). If you buy a physical book and send the publisher a picture of you with it, the publishers will send a copy of the PDF (which is a nice thing that Evil Hats does).
A word of warning - I had read all the books up until the end of Small Favor but missed some of the shorts (until Side Jobs came out) and Our World is full of spoilers for everything. If a character appears in a short story you can expect those events to be touched on in the book.
While the specifics might be hard to understand, you can still get a general feel of the characters without Your Story. For example, after giving a page or two of details about what Red Court Vampires are they give the game statistics (or game stats) for a typical Red Court Vampire. Here are the generic Red Court Vampire game:
High Concept: Red Court Vampire
Skills
Alertness: Fair (+2)
Athletics: Fair (+2)
Deceit: Fair (+2)
Discipline: Fair (+2)
Fists: Good (+3)
Endurance: Fair (+2)
Intimidation: Fair (+2)
Stealth: Good (+3)
All other skills vary depending on the abilities and experience the vampire enjoyed in life.
Powers
Addictive Saliva [–1]
Blood Drinker [–1]
Claws [–1]
Echoes of the Beast [–1]
Flesh Mask [–1]
Feeding Dependency [+1] affecting the following powers:
Cloak of Shadows [–1]
Inhuman Strength [–2]
Inhuman Speed [–2]
Inhuman Recover y [–2]
Inhuman Toughness [–2]
The Catch [+2] to both is sunlight, holy stuff; no armor on belly.
Stress
Mental oo Social oo Hunger ooo
Physical ooo(oo), Armor:1
Notes
Fantastic initiative, Good attacks, Good to Great defense. Can do physical stress with Weapon:3 strength & claws, or set aside the weapon bonus to make it a mental stress attack with their narcotic saliva.
Total Refresh Cost: –11
Most of the things there make sense without YS. The skill all have a description and number (with higher being better). The powers more or less mean what they say they mean and the minus numbers beside them give you an idea how powerful a power is. Total Refresh Cost is basically power level, so you can roughly compare power levels by looking at character's refresh costs.
But you won't buy it for the game stats - Our World is basically a reader's guide to the Dresdenverse and as such it is a great reference book.
