Two games I'd nominate, both on Playstation. Shadowman which is easily the weirdest game I've played, a mixture of voodoo,strange places, the Asylum, Temple of Blood, tattoos, you name it, the game had it. The other is 'Exhumed', a cracking first person shooter, set in ancient Egypt with a great level design and game engine and it's the only game I've played where you had to get on a camel to go to the next level. It was also the first game where I came face to face with a boss that scared me witless. In an area called 'Set Arena'. You dropped down into this place and you couldn't get back out, there were two doors, one on either side, one wouldn't open but when you opened the other one, this demon thing came roaring out. It was truly terrifying because it could jump really high and throw demon skulls at you which killed you pretty quick. It was hard to kill too. It could still give me nightmares.
