Seems so fun! I really don't know why the western release was cancelled...you think kids would ignore this and play on the phone instead?
It does look really fun, great concept.
I imagine they just thought there would be a lack of buyers in the west. Where would you put a machine like that? Not many arcades left, and even if there was, they are mostly populated by older people not children.
I would say things like cinemas and shopping malls, but even then it looks like an expensive machine and the return would take ages to make back (not to mention shits stealing the blocks and maintenance etc.)
