Even genuine collectors break up and sell off most of a job lot anyway since it's pretty unlikely they'll 'need' everything in the lot.|
For example I've bought a job lot of a Megadrive, 32X and so many games before and it was just so I could get the 32X for a decent price, plus selling the rest off individually basically paid for it. I'm guessing your more worried about someone cynically buying the lot solely for profit but the lines are pretty blurry.
Either way if you want everything to go straight to a gamer you want to sell it all individually. Unless you can sell it all to a mate or something your collection just isn't going to stay together.
21 consoles, 5 handhelds, 2 PCs, 1 Mac and about 700 games from the past 30 years. Every major manufacturer and developer represented. Still a fanboy for disagreeing with you.
