My blanket statement for collecting toys - I collect what I want, how I want.
It's was mainly used on my uncle who (still) thinks me pathetic for collecting Transformers since I'm in my twenties (yet, oddly enough, he doesn't comment on my tin toy collection. Go figure). Comments are few and far between these days, so I rarely have use for it anymore, but it still applies.
I have MISB and I have loose figures. I go in and out of phases on how I want to approach my collection, but I definitely have more opened figures than I do sealed.
I realize some people are admittedly opposed to leaving figures in boxes but, well, I'm not. It doesn't have anything to do with resale value (though I'll admit the concept is there, if only because my dad sometimes brings it up on a whim since he's a collector of a variety of things - none of which he's sold, but he keeps the concept of value shove in the back of his head), it's more to do with the fact that I like the box art and how it accents certain figures. It makes them nice display pieces. I'm not so anal that I'd cry if a box were destroyed, but I do take care not to wreck them if I can help it. I just won't have a heart attack if something happens - earthquake, toddler niece, water, etc
So basically (I'm not harping on anyone, just saying) I'll collect in whatever manner I care to. Just because I don't open the boxes doesn't mean I don't appreciate, love or value the toy's existence any less than those who do. I just have a different way of appreciating them than some.
