Well if you do, check out this auction. It's perfect for you. At only $75,000 you could own every single NTSC NES game in box, complete.
The good news is that that calculates into only $69,079.86 Australian. Gotta love that exchange rate.
As well as the NTSC games it also comes with a sizable PAL collection as well as a whole lot of other shit including two NES's themselves and around 50 controllers! I think its fair to say that someone wants to retire.
The action is Buy It Now so if you have the spare money I suggest you either invest in this or at least give it to charity, you rich bastard.
