Miniatures use in RPGs descends from Toy Soldier Play.
But toy soldier play is limited, generally, in scope.
There are other types of imaginative toy play kids engage in, but that stuff doesn't make it into the miniatures use DNA of RPGs.
I'm going take the position that lack of those other types of toy play is a big part of what makes minis use in RPGs suck, and adding it back into the formula in some fashion would vastly increase the joy of minis use in RPGs.
More after work. In the meantime, discuss amongst yourselves this seemingly odd concept.
