There has been a 12th Adventure Architect posted. This series covers the creation of a 2D point & click adventure game from start to finish. When the series ends, the game is complete and will be given away for free:
Think about your favorite adventure games. Gabriel Knight. Monkey Island. Broken Sword. Grim Fandango. The Longest Journey. The stories are very different, but they each have one thing in common: great characters. Whether the goal is to make your way through the Land of the Dead or solve the mystery of the Templars, the reason you care about your quest at all is because you like the characters in the game.
