I'm one of those weirdos that opens everything but keeps the boxes. My biggest problem with windowless was that it upset the standardisation of packaging for my GI Joes, but I get why collectors who don't open would be pissed. If reversing that decision keeps the lines alive then I fully support it.
If you're interested in action figures, there's a
thread that I admittedly don't post enough in, which could do with more plastic sharing goodness.
