Didn’t really pay much attention to the blog, but it’s only been around since January. However, it had the following video, which, to me, seemed very much like some kind of viral marketing video. It looks digitally altered and some of the symbols on the ‘bones’ seem reminiscent of markings in the game.
Hrmmm… if that’s blog marketing it’s pretty bad, as there’s furry porn linked about 5 clicks away on the front page of the main web page you referred to. Maybe there’s a heretofore untapped Ico -> Furry Porn connection I’m unaware of, though.
