Wouldn't you need to prep a spell to increase you volume, as your other spells that boost your performance are going to short out the mike and amps?

I mean you are talking about a Wizard that plays un-pluged all the time, because if he plugs in you get nasty feedback when those amps and speakers blow.

How do you decide which supernatural beings can be played?

All depends on the people around the table.  For instance:
Player 1) Wants to play a pure mortal that has just begun discovering the "Dresdenverse"
Player 2) Wants to play a wizard-in-training
Player 3) Wants to play a red-court infected
Player 4) Wants to play a skinwalker.

Well I am sorry but Player 4 is the odd man out, a higher power level than the rest, and is going to be going solo for most of the story.  Therefore there will be less team building, and long stints of the Storyteller ignoring 3 people around the table while focusing on player 4 and vice versa.  So I would say he needs to come up with another character concept, and tell him NO.

On the other hand . . .
Player 1) wants to play a troll.
Player 2) wants to play a necromancer
Player 3) wants to play a ghoul
Player 4) wants to be a skinwalker.

I would frown at player 4's lack of creativity, (I mean he wanted to play a skinwalker twice now!)  But it would be perfectly fine.  As a storyteller it would be easy to run a dark and evil campaign with the four concepts around the table.

Hellboy
Ghostbusters
The Harry Dresden mov... I mean The Sorcerers Apprentice

You beat me to it luminos!  The Dresden Movie was good, I mean the Sorcerers Apprentice was good.  Okay so how about . . .

Dr. Mordrid (1992)
An unspeakable evil has come into our dimension and wants to rule over Earth, and only a mysterious sorceror known as Doctor Mordrid can stop him.

The Crow (1994)
A man brutally murdered comes back to life as an undead avenger of his and his fiancée's murder.

CrossWorlds (1997)
College good guy Joe is drawn into a battle to save the world from arch-enemy Ferris. Joe's heirloom pendant just happens to be the key to the staff that opens doors to the Crossworlds.

Fallen (1998)
Homicide detective John Hobbes (Denzel Washington) and Edgar Reese, (Elias Koteas) a serial killer proud of his crimes, talk just before the latter is going to be executed in prison. Reese is proud of all his crimes, and doesn't repent at all. Hobbes witnesses the execution of Reese. The killer gets hysterical seconds before dying, shouting it wasn't him. Hobbes starts hearing people on the street singing the same tune that Reese sang in the gas chamber.  He is then told that maybe the fallen angel Azazel is behind it all.

Sixth Sense (1999)
A boy who communicates with spirits that don't know they're dead seeks the help of a disheartened child psychologist.

Thir13en Ghosts (2001)

Night Watch: Nochnoi Dozor (2004)
Among normal humans live the "Others" possessing various supernatural powers. They are divided up into the forces of light and the forces of the dark, who signed a truce several centuries ago to end a devastating battle. Ever since, the forces of light govern the day while the night belongs to their dark opponents. In modern day Moscow the dark Others actually roam the night as vampires while a "Night Watch" of light forces, among them Anton, the movie's protagonist, try to control them and limit their outrage.

Happy watching . . . plus remember you have the Dresden Files TV show you can view.

Nice.  Hadn't thought about using magic to harden the playdoh.

"What are you doing?" asked Simon's colleague as he watched Simon continue to smash a chunk of playdoh against his wallpaper.  "Are you getting a blood spatter off the wall, so you can track the person?"

"No." Answered Simon, frowning at the wall and smashing the lump of playdoh harder.

"Have you already linked to another chunk of the playdoh, and you are pushing here so the effect will happen there?"

"No." Answered Simon, once more frowning at the wall and smashing the lump even harder.

"Well, I give up what are you doing?"

"Trying to get this stain off the wall," Grinned Simon.  "Its been bugging me for days now.  You do know that is what playdoh was originally invented for right?"

Yeah Sam needs the Aspect:
Its over by <place>, <adjective> Mojitos there!

Could be used to know where he is going, as he maps out locals by whats around resturants, bars, and liquor stores.

Could be compels to leave and go get a drink.

All the Vegas Threads are locked.  I think Tbora has let it go to the wayside.  He also posted this.

Heres my idea. It takes place in a way past submerged game, around 18 refresh or so, with 60 skill points.

A group of badass characters who work for what amounts to a supernatural bank or repository protected under the unseelie accords where you might place items of great power when you need it so safe (or hidden) from the unscrupulous who often would try to steal them.In this campaign one of the oldest and most powerful relics (plot device level artifact) that is protected within is suddenly dissapeared so a retrieval team is sent out to find and collect it before it can be put to use.

I don't think the GM would reveal his plans, if he was still planning on running it.

Don't forget about the social side of things . . . There isn't just the physical that hurts out there.

Social - Presence / Rapport Attacks
Minor - Bruised Ego
Moderate - lowered Self Image
Severe - Self-Doubt, Bad Reputation

Social -  Being Intimidated
Minor - Got the Willies, Frazzled
Moderate - Shaken Resolve
Severe -  Lost in Dismay
Extreme - Lost in a Pit of Despair

Social - Being Seduced
Minor - Cheap Thrill, Excited
Moderate - Focused on <person>
Severe - Totally Enthralled

Social - vs Deceit
Minor- I heard something like that before
Moderate - Yeah, I can see that
Severe - True, let me testify to others
Extreme - Never has anything been so true, Unshakable belief

Social - Others
Mild - Got my Guff up, Raised Heckles, Tempted
Moderate - Doubting My Own Purity, Tainted
Severe - Withdrawn, Afraid to Love
Extreme - Ripped Apart Inside, Heartbroken, Catatonic Emotionally

I agree with several that have posted.  There has to be a line.

Question: The Bag Guy in the scene has been stabbed by the swordsman in the group, shot twice by the marksman, he is looking pretty bad, but is still standing. 

Does the Wizard throw a minor bit of magic to "knock him out", because he is worried about killing him?
or
Does the wizard unload with max force to be sure the guy is finished off, since (according to the rules) he doesn't have to worry about killing him?

Part of the thrill in the books I enjoy is the temptation of power that magic gives.  You have to use it responsibly, you cant use it to solve every problem, and if you do over use it, or use it to solve problems it shouldn't be used for bad things happen to you.

Ultimately, its up to each group, each player.  But I would like to see both GM and PC on the edge of the seat when using magic to hurt someone.  Yeah its cool as heck to throw fireballs and lightning blasts around at a whim.  But what happens when the building catches on fire, and the power grid of the city block shorts out.  How many disruptions are going to occur before the over zealous wizard(s) are hunted by the authorities as terrorists, and the wardens as rogue warlocks?

So start with B but if the players abuse it, then switch it to A.  They will have to learn to pull the punches so you can switch back to B.  Perhaps there is no clear defined answer on this.  But abuse is a two way street.  Player and GM should share the responsibility.
