Shadowgate

[Punisher Rising]

Does anyone remember this game for the NES? It's a point and click game that's something of a hybrid of a puzzle game, adventure and survival horror. It's a bit Saw-like in the sense you're trapped in an enclosure where many death traps and dangers await you around every corner and there's countless ways you can die. This game is actually pretty spooky and very atmospheric, and if you have the patience it's a great game and worth a play. Here's some video segments of the game, and be forewarned it has some spoilers for those of you who don't want the story ruined:
