Right off the bat, being a Hunter is awesome. Being a normal human with nothing but a shotgun and a buttload of courage between you and the creatures that stalk the night is automatically cool, and very hard to screw up.
That said, I do have some thoughts.
One of the underlying themes of just about every White Wolf game is the "transformation", where your character goes from being normal to extraordinary. It's your Embrace, your First Change, your Chrysalis (yes, I did have to look that up), etc. Now the one group that wouldn't necessarily need this is the hunters. But they get one anyway. This kind of takes away from the hunter feel, changing something that should be natural into something supernatural. It should be just average guys suddenly realizing the horrifying truth for themselves, not suddenly, miraculously seeing monsters everywhere.
Along the same line, the Hunters' Gifts seem kind of off. I think that if I were to play Hunter, each Gift would have to be tailored specifically to a character. A priest would think it was the wrath of God, for instance, while a punk biker would think it was his hatred unleashed. What I'm trying to say is that Hunter Gifts should always be a part of the hunter, not "special powers" that all hunters have. So someone should never tell a Judge "Hey, Jim, could you Discern that guy in the corner? He looks kinda fishy." It should be "Jim, you can see these things. What do you think of that guy in the corner?"
The other thing wrong with Hunter is that it doesn't seem to cross over too well with the other games. While an NPC hunter might be hell-bent on killing the Garou pack that's moved onto the farmers' land, a PC hunter will be far more sympathetic to the werewolve's cause once the local Silent Strider explains things or the local Child of Gaia patches up the wounds he got from the local Get of Fenris. It crosses over a bit better with Vampire, because no matter how sympathetic the Kindred is he still feeds off people. No hunter in his right mind would listen to a Toreador trying to explain how his ghouls WANT to be fed on.
One thing that was rather disappointing about Hunter is that it doesn't let you play as an Inquisitor, but on second thought this does make sense because a lot of Hunter is based on not understanding what you hunt, while Inquisitors do know a lot about the stuff they hunt (especially vampires!). You can, however, play a priest who's not in the Society of Leopold, and who gets his call on his own.
Okay, back to the good points. It's very cool to be a guy in a trenchcoat chasing some dark thing down a back alley with a shotgun. That belongs in the World of Darkness just as surely as a Nosferatu following a prostitute from the shadows or a Red Talon tearing out a poacher's throat in front of the horrified eyes of the other poachers.
Actually if you ask me, Hunter belongs in the World of Darkness way more than a lot of these new games, like Demon and Mummy, and deserves a closer look and some more stuff.
Right, now that that's done I can say... wait... what the heck... I coulda sworn I saw something run past my window. Just gimme a minute, lemme grab my shotgun and check out what it was. Probably just my imagination, but you never know...
