Hello Mr ducksauce, and thank you for your input.
You have a point about Outdoorsman. I might also allow the Survival skill to modify Stealth or Investigation, but I wanted another Survival stunt for the Hunter generic NPC and I was having trouble thinking of one. Your rewrite of Outdoorsman is reasonable, but looks pretty weak in comparison to stunts like Tireless and Supreme Concentration.
As for your list of stunts (you totally do have a list):
Everybody's Buddy, Money Talks, and Poker Face look great. I might just steal them.
They're In The Trees and Without A Trace should probably be merged.
I like the ideas behind Empty Mag Empty Room, Spin Doctor, and the Stealth attack stunts, but I think you ought to alter the mechanics behind them.
Peforming spray attacks with any firearm as a stunt is in Our World already. (It's called Blaze Away). Personally, I think that Empty Mag Empty Room would work well as an upgrade to Blaze Away. Something like this:
Empty Mag Empty Room (Guns): (Requires Blaze Away) Sometimes you just have to fire every bullet you have. When you attack with a gun, you may choose to fire every bullet in your gun at once. If you do, each attack you make that exchange gets a +1 bonus.
HobbitGuy is right about Spin Doctor: stunts can only provide two mild consequences if they are restricted in the situations that they can be used in. Perhaps Spin Doctor only works against attempts to make you look bad to others?
I'm not really sure how to make the Stealth attack stunts work. Dodging with stealth could be a stunt with no special rules, but I'm not sure how to justify using Stealth for attacking.
Finally: I'm thinking of compiling everyting in a big list on the first post and sending that list to the DFRPG Fan Resources page. If I do, can I use your stuff?
