I really like adventure games, and I've found a few online for free!
Please check out this page at Wikipedia to learn what an Adventure Game is if you're not sure!! http://en.wikipedia.org/wiki/Adventure_gameHere are a few sites I hope I can keep adding to this:
http://www.agdinteractive.com/ They're trying to remake a few classic adventure games here like
Kings Quest, and they've done a marvelous job too! Make sure you download the sound and music files they add a whole new depth to these revamped games.
http://www.studiotrophis.com/wc.php The White Chamber is a horror sci-fi thriller adventure game. There are a few different endings in this game that you can access depending on your actions.
http://www.homestarrunner.com/games.html Just blow up the
Peasent Quest ship to play a satirical adventrue game courtesy of the brothers Chaps. I admit that I had to find a walkthrough for this game some bits just don't make any sense despite the hilarity.
http://www.abc.net.au/chiko/ Chiko Accidental Alien is an educational adventure game with lots of puzzle style mini games to challenge as you advance through a fun park style alien world with your ultimate goal being to return to earth.

Choco Museum its really a scrolling click game for flash media but it has a strong adventure game feel to it.
http://games.mvm.com/halloween/halloween.html K-mart's Haunted House is a plug for K-mart products put together into an experiment of advertisement evyl gone horribly right! The game is cute short and a bit of fun.. there even is a last boss of sorts he's kind of a celebrity too! The game took me 12 minutes my first go around, oh and the character outfit selection for this game is sweet!
http://www.adom.de/ Acient Domains of Mystery or ADOM
This game is very complicated and if I remember correctly it has text based graphics, but the adventure is certainly there take a look! (We can Thank Harried for sending this our way.)

The Kingdom of Loathing is a 2D sticks graphics MMORPG of sorts with a definete adventure game feel to it. The game is filled with punny and parody style humor, while the economy of the game revolves around meat as a currency, plus the character classes are an absoulte hoot! I'd swear by my liver of steal that you'll at least get a smile out of this ackwardly rerfreshing game.
