Microsoft only had one live game demonstration at the Tokyo Xbox Summit today. Towards the end of the conference, Square Enix producer Hiromichi Tanaka took the stage, shared the E3 Final Fantasy XI trailer with the audience, then proceeded to play the game right before our eyes.
The version of the game played by Tanaka features the most recent Final Fantasy XI world updates and runs on the actually Xbox 360 hardware. If you want a first look at how FFXI will look and play on the 360, download our two gameplay videos in the video section below (Tanaka didn't play too well because he was speaking).
In closing, Tanaka assured that Final Fantasy XI's beta test is still on track to kick off with the launch of the 360 later this year. He even went so far as to say that the beta test will occur on a previously unseen scale.
