i dont know which to vote so...
along the lines of dead bodies, how about skeletons...like with indididual bones segments...upper leg, lower leg, upper arm, lower arm, spinal cord.
those could work for anything from GW conversions to D&D monsters. for 40k i know the bones could help people who cant make reasonable ones from sculpting but can then use them easily.
something mising from fantasy RPG minis to show placement of things in dungeons...rest areas....latrines...old fashioned hole in the ground TOILETS!
you cant possibly tell me a wizard in a tower lives there most his life and never has to go...its got to be in a room somewhere!
how about bases with water...like say the round bases for GW...just a round base with a flowing water design on it. they could them be used for mud, water, lava...anything that flows or oozes across the ground.
well those are a couple of my crazy ideas.
probably only things i would think of or even use.
