There are two games over at http://www.intelligentgear.com/ that are free to play:

Base Ship Commander: Base Ship Commander challenges your leadership skill as a Base Ship commander fighting a war for Galactic Domination against four opposing empires. Develop the strengths / abilities of your Base Ship, set tactical priorities, and conquer enemy planets while devastating enemy ships. Base Ship Commander is a tick based game that runs for about 4 weeks for each round played. The next round starts Monday.

Gear Combat Arena (beta): Within the Gear Combat Arena, you manage and maintain a Combat Gear that competes in a futuristic sports combat arena. Each Gear is equiped with a Chaingun, Mortar, Scanner, Shields, Cloak and Mine Rack, all of which can be upgraded as the game progresses using "in game currency". In addition to the listed devices, each Gear can research, and develop Nano Byte Augments, or Nano Mods that provide the gear with passive attacks. Each player must maintain the combat capabilities (and decisions) of a Gear using an Arena Script. The Arena Script controls the actions of the Gear during a Combat Match. Gear Combat Arena (beta) is a tick based game that runs for about 4 weeks for each tournament played.
