Have you checked your sanity lately?
So, instead of a real in-depth review, I'm simply going to give a quick summary of the game, followed by a possible recommendation.
Amnesia: The Dark Descent combines the mystery and intrigue of a point-and-click adventure game with terrifying, hellish nightmares straight from the ghost of H.P. Lovecraft. Not only does this game make you completely vulnerable by stripping you of any means of defending yourself from the unnatural horrors that dwell within Brennenburg Castle, but it also reminds you how fragile the human mind is. Witnessing disturbing events, looking at monsters, and standing in the dark for too long all take a tole on your sanity. And when your sanity crumbles, the real freaky s*** begins. All you have on you is a lantern with VERY limited oil, a finite supply of tinderboxes to light torches that are scattered around the castle, and your own personal wits.
I've made it as far as maybe 1/4 through the entirety of Amnesia. And in all honesty, it's going to take a miracle for me to muster the willpower to boot it back up again and progress. This game is so legitimately terrifying that it can scare people away from playing it. I'm unsure if that's a good thing or not.
So, would I recommend Amnesia: The Dark Descent? I say "Maybe". If you're looking for a game that's fun, don't bother. Games like this one aren't meant to be "fun", they're meant to make you unnerved, disturbed, lost, and vulnerable. But if that's the kind of experience you're looking for, especially in a gaming generation where the majority of "horror" games are composed of shooty-shooty action, gore and jumpscares, then Amnesia will surely give you a true survival horror experience.
As a final note: ignore the number score and "classification" that I've chosen for Amnesia. If I could, I wouldn't give it anything, as I don't feel it's justified since I have yet to complete the game.
