That 'Suqare' Enix has to be a typo, right?

more like Parody. Very common in japan for artist and even official animes to "mispell" copyrighted stuff to avoid...well copyright.

There is no such thing as "Free advertisement", cause thats considered now a "Conflict of interest". SO you could actually get in trouble if said company actually does want to sue for not getting their permission to use their brand.
