Survival horror is arguably my favorite genre in gaming. There's just something masochistically enjoyable about getting so immersed in a game that a book falling off a shelf makes me shit my pants. Silent Hill has always been my favorite horror series, it got under my skin like nothing else. Yet I dare say that Amnesia terrified me even more than that. Mind you, I'm not saying it's overall scarier or better, they're very different games, and I rarely pick favorites. But holy fucking bitch tits, I have never felt so terrified trying to hide or run from those monsters, or even the occasional inanimate object. Hiding behind a box staring at the ground as something breaks the door down, thinking "oh god I hope it can't see me oh fuck just look at the ground, just don't move an inch, just go away oh fuck".
Those fucking... THINGS, man
The only thing I'd say wasn't 100% would be the ending(s). It seemed a little weird and lackluster, but I'm not saying it's bad at all. I was still thinking "man fuck this shit, I'm out of here". That and the lack of replay value, but hey, I'd say it was WELL worth $20.
It is depressing in a way though, it seems like the true survival-horror genre is dying in gaming, and I'm betting it will be a long time, if ever, before another game this good comes out. But hey, I'm still ever the optimist.
On a side note, holy shit 100 followers! You guys are awesome, keep up the support and I'll keep up mine.
