If you haven't yet, I'd definitely try BLOOD...great fun for the horror enthusiast.
Why not try a Clive Barker game *before* he made the shitty Jericho?
Check out "The Undying".
My other personal recos are "Star Trek Elite Force 2" and "Unreal/2".

There's some other shit.
I also hear good things about "Blake Stone" and "Rise of the Triad"
