Making it a cardboard box based thing is stupid, in a way. Unless they sell replacement boards for a buck each or less, this will bring parents to the brink of bankruptcy. Eighty bucks, sheesh. Plus replacements, because even with stringent controls and handholding, this shit will disintegrate quite quickly, or never get built in the first place.
Other than that... I would have loved shit like that as a kid. Provided it takes longer than just five minutes until the cardboard is worn out. Which is about as long as my attention span would have lasted, probably.
