Funny that you dug up this thread! I'm currently playing some Uninvited on a Mac Plus. It was a spooky game for its time!
If this is it, wow.

Dead Space and Silent Hill 3 are the only two games that have ever creeped me out to the point that I did not finish them.
Dead Space has very high production values especially when your character is being ripped to pieces. Did you ever play Doom3? It reminds me of DS.
Yeah, yeah. AvP got me too, but worse was Clive Barker's Undying!
Oh my God!
I've heard that Bioshock has its own moments.
Bioshock has tremendous atmosphere and superb Art Deco design. However it was so oppressive living this nightmare under the sea, I did not finish it.
