Concerning the game itself:

"Sculptures, paintings and action figures do not have utilitarian aspects and are therefore generally copyrighted as works of fine art. On the other hand, ordinary alarm clocks, dinner plates, gaming consoles or other objects of daily use are usually not copyrightable."

This is a complete game with a utility. (It isn't like a game figurine that can be considered a work of art and only part of a utility product but more like a gaming console with a nice design that cannot be separated from the product)
