I sort of feel that these issues are part what you said, exactly, and partly about collector and completionist impulses, partly about community status and positioning, partly about the odd liminal zone of friendship and consumerism where you pay money to play products of freinds design that maybe sometimes you helped create, partly about different expectations of play (both between groups and within ourselves, and between ourselves now and ourselves ten years ago when we put down our unexamined expectations about what play is), partly about market forces and how little we actually understand them, and… Probably more.
It is, in short, a mess.
