Not to mention the typographical errors in names that are either previously established, trademarked, or universally written in a particular way, there.
The event's name is "Nintendo Spotlight: E3 2017" with no "at" or "@", Dream Land has been incorrectly written as "Dreamland", and WWII has been written as "WW II". Moreover, calling Monster Hunter XX "Monster Hunter Generations 2" goes against Capcom's naming convention for non-sequel expanded versions of the Monster Hunter games.
There's plenty more wrong, but that would lead me way off-topic. Still, there's our first "badly-photographed sheet of paper" hoax for this year.
Anyway, even though this is fake and such a thing would almost certainly never be made, I do like the idea, because the distinctly Japanese lore that influenced Super Mario Land, which really wasn't localised out to any noticeable degree, could lend itself to some really great ideas for ghosts. I mean, they could quite easily get away with drawing from all sorts of youkai lore wholesale, and they could even throw in the Pionpi enemies for a comical jump-scare (pun fully intended).
