Hi peoples. I realize I'm a little late to this discussion, but I've read most of the posts. Everyone seems to have perfectly good reasons to collect the way they do. I'm sure if all had an unlimited supply of money and space, we would all get at least 2 of each figure, one to open and one to keep MISB.
For me, I really appreciate the boxes. Especially vintage box art. But I open and display, and here is why:
This is what I see when I walk past my "spare bedroom". I smile almost every time. If I get the urge, I'll take a detour, grab a figure, and changes his mode, stance, arrangement. If I get bored, I can utilize my collection for fun, by making new displays, pairing up iconic figures, or pulling out a rare TF just to leave out in my living room and be awesome! (my wife hates it when Fort Max comes over for dinner)
One of my best friends in the world I met at Botcon last year. He collects MISB only, and he got sick and lost sleep the one time he open a figure, which was not rare in the least. He absolutely fears a dinged corner, or a faded cardback, and the poor guy is stressed out! I give him a hard time, but to each his own.
Anyways, I think we can all appreciate the hobby, however you do it. Plus, what a bunch of wonderful pieces you all have! Great stuff, in or out of the box!
