Eternal Darkness falls into the category of action horror, and deliverrs hours of gameplay. First of all, there is the innovative sanity system. The more enemies you run into, the less sanity you have, however killing these enemies will increase yuour sanity. If your sanity falls to 0, the camera will tweak out, and your character will become very hard to control. Another great aspect of the game is its magic system. Though accessing the spell menu is sort of awkward, it work ok. You use runes construct different spells, and destroy various beasts. I give Eternal Darkness:Sanities Requium a 10/10.
