That’s an interesting thought and I think it varies depending on the collector. I for one have a very small 6 scale collection. I don’t collect franchises or runs and don’t hone in on a specific format. My collection is focused on just a few of my all time favorite characters with a few second tier listers. I treat 6 scale figures as center pieces. I used to collect various figure lines (smaller scale) but realized I didn’t care for 90% of them and they were just taking up space.I always found it interesting ppl who would buy multiples of the same figure to display the potential different looks the figure is possible to have with it's included accessories rather than just displaying it one way for a time, then use those parts to switch up the display at a later time. To me, that's part of the fun of having so many extra accessories. That's sort of why the idea of two packs is a little strange to me unless the second is something entirely different. Like with the TDK Joker, even if InArt wanted to still included the Jail set up, I don't feel there was a need for an entirely second figure when I can just take the coats off and swap the arms myself
I have a fine-tuned Batman collection that hardly has any villains or side characters and of many different formats. I’m sure that’s weird to many haha. I particularly love to collect artist renditions as well as film, animated, and video game renditions etc. I’m still waiting to add a 6 scale Batman…some day…I’m just so picky. I also have a small Mandalorian collection consisting of Lego vehicle builds and a few small figures and so on with a couple 6 scale Mandos representing his different stages. I’m planning to do the same with Aragorn. I still keep my ToyBiz Helms Deep Aragorn on my display shelf from back in the day.
As for 6 scale, Im not much of a poser/photographer, but I love the tangibility and accuracy of the format. I’ll occasionally repose but hardly.
I guess because of all this, I have no problem justifying having more than one of the same character. I don’t care to collect side characters or fill shelves with cheapo crap unless it has some kind of nostalgic value. I’d much rather buy another or attempt to create another iteration of the same character rather than fill space with characters I don’t connect with. That’s really what it boils down to.
