This game scared the crap out of me back in... 2001. I could only play it for 20-30 minute stretches before I had to stop and relax a little. Just thinking about the whispers of "Scryyyyyyye" gives me the willies. It's not without it's flaws *cough final boss fight cough* but a very enjoyable game. Using the... raise undead (?) power on a living pirate was one of my biggest "OH SH*T" moments ever in gaming.
