Aye, when they started moving the camera angle manually during the other video my mind was blown. xD

As for what it has to do with FF - not too much, although I'm fairly certain it was stated at some point that they wanted to give an FF theme/feel to the tech demo, which I personally think they did successfully. Being shot at by soldiers while you control someone who relies on magic, has healing abilities, carries around a crystal and does a summoning. Meanwhile the soldiers who were shooting at you unleash one of their super-dogs, which is a common thing amongst FF enemies (soldiers and monsters working side-by-side, often dogs). And then there's the whole thing with starting off in the slums and then having the wonderous revelation of the rest of the high-technology world.
