I realize I am in the smaller section of miniatures gaming
in that I am drifting towards 3 mm for mass battles and retirement space concerns is driving me from 25+ mm skirmish, small battle games to "TBD" but my impression is that the offerings are providing what is "currently Kewl" (which is not a bad thing, just market driven,)
Fantasy/Science Fiction/VSF because it can sell well
and what is not available for historical gaming (sometimes called niche miniatures) in part because these may be what the sculptors are interested in.
I would like to see more 15 mm stuff to replace my 25+ mm figures but how (for example) niche is 1700's Soldados? Way niche!
When the demand is there the KS scene will reflect it I am sure.
Gracias,
Glenn
