The anime is not really good in my opinion, they give so much fillers in the anime, and that's ruined the whole story. But the manga, is just great, and it's very unique. The manga doesnt have as much fillers as the anime does, and that's a plus (well, they just have 1/2 fillers i think, I dont remember..)

I recommend to reading the manga, rather than watching the anime.

As you guys know, Fatal Frame is a horror game. So I will just recommend this game for people who love to have an adventure through empty village, where the village have a scary history and ghost and forbidden rituals. So, it's just for people with a strong heart xD I mean, if you are get shocked with the first scene, do not play it. Seriously.
The horror scenery on the game is really great. The darkness, the character's weakness, it will makes you feel like you are unable to do anything. Fatal Frame is not like the other horror games, which have the ability to destroy the ghost with their weapons. In this game, your weapon is just a single camera. And there is one chapter where you are dropped the camera and you cannot fight the ghost back.
I am enjoyed playing this game.
