I think that most of us will end up checking all the boxes (the one about children being problematic) as the hobby grows with us and vice versa. I migrated over from a wargaming/historical point of view which was both role-playing, play and collecting, but I find that Playmobil allows me to infuse my characters with more depth than other scales allowed.
I recently purchased a small lot of klickys on EBay thinking of them as parts for the 'bins' but as soon as I saw them they all had names and personalities (and now they have their own box)! The figures seem to strike a respondent chord and allow our perceptions to grow in unintended ways, which is fine with me! I find I enjoy displaying them as much as I can, especially around the holidays but my photographs are more to record unrealized story lines and to be sure I can recreate certain customs.
