A word on Splatterhouse-one of my favorite series, and one thing I always liked a LOT was the music from Splatterhouse 2, especially Level 3: The River Of Death. It's absolutely chilling

Give this a listen:

Getting back to the question: Some PC hames I forgot to mention:

If I hadn't mentioned before, I also liked the Blood Omen series a lot. Kain was like an undead Vegeta-he was evil, but had a necessary place in the outcome of things when it came to the overall picture.  An undead protagonist of sorts. The voice work by the now-deceased Simon Templeman ( or so I heard ) was great too.

The Hitman series was another big fave, as was EA's flight sim of the Apache, entitled The Longbow Anthology.  There was a hack\slash\dismember game called Blade Of Darkness that was fun too.
