I think for me the most interesting part of that trailer was noticing a very distinct western influence - then finding out Crystal Dynamics and a Canadian composer were involved. The potential for Eidos studios to create something with Square Enix is most interesting. Can't say the trailer itself (if it was for a real game) was super exciting, but the fusion of Iranian vocals with western art and Japanese direction is something I'm sure Square Enix are hoping can change the Japanese RPG.

Either that or they just did it without any of that in mind. :)
