Just watched the whole video. My thoughts are maybe the compression was bad and I was watching a bad youtube video because it was choppy as hell. Hopefully youtube is the reason for the crappy framerate. Also, a lot of ridiculous hairdos. Like performance crippling stupid (possibly), as well as stupid looking in general.
On the plus side, I finally think I saw a person not white (or whatever the word it is when Japanese try to make things universal but essentially make their avatars white) and that was nice. Admittedly I haven't engulfed all the media between this and the cg movie, but I have half been watching it a bit and I think it's nice to place a fry cook person of color in the game as a nod to the existence of people of color.
On the non sarcastic up side, after the first 30 minutes of the video, it did start to get interesting. The combat in the first bit was boring, but both the combat and the story were kinda interesting by the end. I collected the crap out of monsters in FFX, so if the diner missions are a collectathon end game leading to a fight with an ultimate monster, then that would be fun.
