Greetings Juju and luffy. Glad to hear you're still into this. Anyway, I have not read the horror recognition guide, but I am a good fan of Hunter: The Vigil. It is my favorite World of Darkness game for a number of reasons. First of all, your characters are the Underdogs, most of the time you're playing normal humans who have decided to go out and hunt monsters to protect humanity. Of course your characters are no match for fighting monsters in a toe to toe fight and against most supernaturals they will be at a disadvantage if not outclassed completely. It is also the fact that as a hunter, you're forced into a life that alienates you from normal society. You're going to have to do some pretty illegal stuff and immoral stuff in order to succeed which can take a toll on your Morality. Stealing, breaking and entering, stalking, vandalism, murder, arson and numerous other crimes will be done in the process of the Vigil in order to defeat your foes. Much of the time, your so called good deeds will not be rewarded and to society as a whole you will be seen as just another violent criminal. To survive as a hunter you need to work outside the system and use what advantages you can get. Keep your identity hidden for if the monsters know who you are, your life and the lives of those you love are in danger. Do not jump the gun and act impulsively, a direct assault can quickly leave your cell in a bad situation. Investigate your target, get an idea of what they're capable of and plan an attack where you can defeat your foe with tactical precision and intelligent use of equipment. But don't get married to the plan, for many plans do not survive the first encounter with the enemy. You must grow and adapt to every situation if you are to survive at all.
Perhaps if you live long enough, you may find aid in the Vigil. There are numerous secret societies of hunters throughout the world that can provide you support although many of them have clandestine agendas of their own in the hunt. Then again, you may just remain as a lone sheep with a shotgun fighting against a jungle of predators. But in the end, the life of a hunter is one with a low life expectancy. You may have a heroic death against the creatures of darkness if you're lucky. But there are fates worse than death for those who take up the Vigil. A vengeful werewolf could break into your ex-wife's home and murder your family after discovering that you killed his pack-mate. A vampire power-broker clean out your bank account leaving you without the resources to protect yourself from a hit-squad sent to rub you out. But most of all, the worst enemy can be yourself, for hunters see things that normal men are not meant to know and do things that are sometimes worse that the monsters they hunt. This leads them down a trail of madness. You may just end up in a happy home for the rest of your life. Or worse, you may become a Slasher, a "Human" monster who kills not just monsters but regular people as well. In time Slashers can evolve gaining supernatural powers from their madness and by then you're no different that the monsters you once hunted.
This is what I like about Hunter: The Vigil. It IS the horror game of the World of Darkness. As for the Horror Recognition Guide idea, I don't think it works very well for a changeling game. The thing about changelings is their diversity of backgrounds and how they mesh together due to mutual protection and acceptance. Yes, hunters CAN be captured by the Gentry. In fact, because they actively seek out the supernatural, they have a greater chance of crossing the path of a Gentry than a normal person. But when a Hunter becomes a Changeling, their life priorities change and the prospect of hunting down monsters for humanity's sake is put on the back-burner to the various complexities of changeling existence. Not to mention you're no longer human and to fuel your powers you have to feed on people's emotions, something a hunter might find revolting. Although feeding on Glamour does not cause any physical harm to a mortal (Well usually, the process of invoking such emotions could cause some harm to a human) a hunter would not see things that way. Of course Changelings are often hard to hunt considering the mask is such a powerful illusion. Most hunters do not have means of piercing the mask. Still as contracts still have visible effects, changelings can still be discovered and killed by hunters who discover them. Anyway there is my 0.02 cents on the idea.
