Time for the Eternal Darkness Guru to clear things up.
Eternal Darkness: Sanity's Requiem is not a survival horror. Sorry, it just isn't. You don't have limited saves, and with the swords, you can't really say a thing about limited ammo. Survival horrors usually give you the sense of being trapped, and you need to conserve your ammo and solve puzzles and BLAH BLAH BLAH, it's all to complicated. In Eternal Darkness, you get spells, and badass weapons that no survival horror would be bold enough to use. Assault rifles, huge fuckin swords, and MAGIC... and the game is better than any survival horror anyway. There's no Alone in the Dark style crap with the bad-graphics character walking around on a high-res background. No bad camera angles that won't let you see the damn enemy that's about to bite you. Damn those camera angles.
The point is, survival horrors suck. Maybe Eternal Darkness doesn't. Eternal Darkness is a horror, but there's no survival about it. When you can use spells to heal yourself, it takes away the whole point of a survival.
