For me, crack it open. A toy in it's box does me no good whatsoever. I used to keep certain toys sealed back when I was collecting for potential resale value, but when I wound up getting royally screwed by both Playmates' Star Trek and Star Wars Episode I toys I just collect the things I wanna fiddle with and that's it. So what about you? Do you open and fiddle or keep 'em sealed on the shelf?
