I would have to say Resident Evil for GC.
Eternal Darkness would have gotten my vote, but it has a couple problems: 1) It lets you know your character's sanity level and 2) It lets you heal your sanity with spells.
If they would have kept you guessing more by not letting you see a sanity gauge, that would help (maybe use some on screen effects). Secondly, it should not be so easy to heal sanity. After playing the game thru once, I usually had my sanity full unless I banned myself from using the healing spell.
Also, they need more sanity effects that you cannot tell that it is a sanity effect. Keep you guessing. To make it harder to tell if it is a sanity effect, they need some weird **** that is real (not a sanity effect).
That is why I was always looking forward to Eternal Darkness 2. I thought the first one was a good trial run for a great game.
