Clue

I picked up a complete copy of Clue for the SNES about a week or two ago.  This game is dirt cheap, so it's really easy to find a nice copy.  I used to like Clue as a kid, so I rented the SNES version of the game around mid '90s to see what it was like.  The game was a lot of fun and did a great job of conveying the dark, mysterious mansion setting.  If you like Clue, I highly recommend this game.  It's much better than any of the later versions that came out.
