To start off, I found...

Item: The Goat in the Grey Fedora
Type: Game
Link: http://www.otterarchives.com/bounty2/bounty2.html
Descrip: To quote jayisgames.com:
"a strange and offbeat point-and-click adventure with a black and white film noir atmosphere. The game's highpoint is definitely its sense of humor. Not only that, it actually has a plotline, which, as the title implies, has to do with a goat. In a grey fedora. "

It's reminiscent of games like Monkey Island and is really funny, especially if you can pick up on all the noir movie references. The character's are excellently voice cast, the script is highly well written and although short is an excellent game to play for half an hour. If you find it interesting check out the first game in the series, A Case of the Crabs (http://www.otterarchives.com/bountygame.html).

Item: The Seven Noble Kinsmen: A Shakespeare Murder Mystery
Type: Game
Link: http://www.bbc.co.uk/drama/shakespeare/game.shtml
Descrip: Perhaps the most original murder mystery concept I've ever seen.
The game throws in more mystery, sometimes-creepy-but-overall-cool-looking visuals and Shakespeare quotes then you can shake a stick at.

Essentially the story is this self-proclaimed genius, Christopher Morton, created this play that involves 7 famous characters of Shakespeare and used many various elements from his plays to do so. However after one horrible review from a critic, the play panned and closed after a week. All the actors' careers were devastated and Morton disappeared from the public eye. 5 years later all the 7 actors, plus one other person, are given invitations to hear a reading by Morton at The Knell, Morton's private theatre on the Scottish Isles. That other person is the Critic, you!

Obviously things go awry and its up to you play whodunit.
You need to register in order to play, but all it requires is a username and password, no email of any kind.
Note: Some scenes are a bit graphic (not really but still a bit unsettling for the easily squeamish) so you may need to avert your eyes once in a while but overall the game is good for anyone.

(Sorry if this is a bit longwinded, I seem to have a habit of doing that. Please feel free to write as short of a description as you like, much shorter then this if possible.)
