This week's update to GameTap adds Age of Mythology: Gold Edition and Fishdom to their subscription area, and declares the original Fallout their free game of the week. They've also rotated five other games into their free area, where they will remain for about three months. These games are Cuban Missile Crisis: The Aftermath, Jagged Alliance 2 Gold, Psychonauts, Earthworm Jim, and King of the Monsters 2, the latter two of which can be played in a browser. This page has the complete list of their free offerings.
