Update: Thanks for all the interest in the giveaway, but our supply of beta keys is finally exhausted. Those interested in checking out the beta test of Age of Empires Online can head over to the Games For Windows Marketplace between now and 3:00 pm EDT on Saturday to gain access. There have been reports that the beta will conclude on Saturday, but we're told this is not the case, and the beta will continue past then. It's not completely clear if these signups will enable you to play past that point, however, so those looking to hedge against that possibility can reply to this thread and request one of our still-substantial supply of beta keys, and we'll send one along. As before, Games for Windows LIVE is required. Update: Thanks for all the interest in the giveaway, but our supply of beta keys is finally exhausted.
