They always come out of the box, and briefly get displayed. But eventually they end up back in the box (or anyway a box) and shoved in the closet. There's just not enough room to display everything. Plus I get tired of dusting it all. Some day I may assemble one of those displays with multiple Batman figs, multiple Superman figs, etc acquired over a lifetime, but until then I only have room for one or two of each, and they get put out in rotation.This is where you guys are going off the rails, toys are for taking out of the box and displaying or playing with them. THIS is the reason I don't buy everything that comes out, I wait for stuff that really appeals to me.
In a few more years, we'll be empty nesters, so maybe I can reclaim one of the kids' rooms as an "office" or man cave and put more stuff out. Then I'll have the fun of digging things out and saying, "Oh wow, I bought one of those!"
But I don't buy everything that comes out, nor (alas) even everything that appeals to me. Usually enough time passes between purchases that I'm put off by inflation when something does catch my eye, and I take a pass. For instance, I don't care how nice the Mezco figs look, if you'd told me when I was younger that someday 6-inch action figures would go for $100 a pop -- and that they'd routinely sell out! -- I'd have said you were nuts. At some point, I seem to have crossed over from "Sure it's pricey but I gotta have it" youth to "Sure it's awesome, but that's way too much" old age. My sweet spot seems to have been the 90s, when I bought way more stuff than I needed. And looking at some of it now, I think, "Wait, why did I want that, again?"
