They all look to be in really good condition too. So it was probably an over the top collectard that justified the insane price tag.
I like cardboard as much as the next guy, it's cool having the original box. But I think it's safe to say that normal people would never pay this type of premium. It's precedented Ebay sales like this that are ruining even owning TG16 boxes. I've found a lot of my stuff wild, or gotten for free buying other stuff from sellers. But it's getting to the point where the cardboard for a game like Hero Tonma could land me a huge PCE trade. Like it's becoming "so valuable on eBay" I could trade with some crazed box collector and get all of his best PCE games, and run away like a bandit.
