Tell me again how you make a copy of an NES cartridge? So you can’t just copy it to another cartridge unless you can dig up a whole bunch of out of production hardware and start manufacturing the cartridge hardware again. The supply of cartridges of a single game are fixed and won’t be going up.
People spend tons of money on crappy old Chevies, put them on plinths and then don’t drive them. This isn’t any different. Again, the collectability is the thing.
Well ya got me there, I figured somebody would have hacked them. Or made reproductions. Emulators. I don’t believe I’ve ever played any of those games. Do you suppose they are actually going to play it, or is it going to be displayed on a shelf, and subject to veneration?
