Still recall some people on forums telling me that it would have been perfectly OK to sell my rares, cause one could always just buy them back later when the market cooled off. Heh.
I don't universally look down on the current market buyers, as surely some of them really are well off enough as adults that it's not that big an expense for them, and not all carts are super expensive. Though, as a quality over quantity person, I don't "get" completionists who need rooms full of two copies of every version of every game, as if it's a stamp collection.
Also notice that the old school people who grabbed their carts back in the day are hardly ever the ones posting YouTube videos showing off their collections or setups, it's mostly relatively new collectors and seemingly super rich euro completionists who do that. Not sure what that says about the scene, but it's funny how that goes. Though, to be fair, I tend to enjoy seeing peoples' setups and collections, so I have mixed feelings about it.
I occasionally ponder dropping some cash on one of the few rares that got away from me over the years myself, though I never seem to get around to actually doing so. It does, admittedly, feel like a bad deal nowadays when never having paid anything even close to current rates for a cart in the past.
For what it's worth, I do play my carts when I have time, and recently got back into the fighting games more, with an increasing appreciation for their finer qualities now that something finally clicked and I don't completely suck quite as much at them. Didn't know what I was missing, it feels like suddenly understanding the technical aspects of music or something.
