I respect dude's commitment. Honestly, I wish I kept everything of mine through the years. I let my father talk me into selling my Nintendo and games when I was a kid who wanted a Genesis, plus we were poor.
Kept gaming through my teens and early 20s, but with having buls**t jobs, I was always looking for a way to drop the cost on games. Now I'm a 27-year-old man, filled with regret.
On the bright side, I haven't traded in anything in a little more than two years. I don't even buy used anymore, because 1) developers need the money, and 2) I hate the used-sticker residue on my game cases.
Regardless, I can't understand what my dude on eBay is doing right here. He's selling the lot for his convenience, but I doubt any prospective buyers have all the consoles needed to play that. Who's going to drop Gs to get a console collection for a system they don't have?
And like someone else said, we need to know what's in there. Not everyone else is like me, refusing to pay used at Gamestop, but why buy an entire lot if you can pick up specifics elsewhere?
