some guy made these meeples for Lords of Waterdeep:
and later i saw these painted meeples at a store:
and it gave me an idea:
what about a series of meeples in a couple of archetypal shapes and sizes, accompanied by sticker sheets
with images of monsters and PC/NPC figures to fit them?
it would be much cheaper then even unpainted plastic minis, you could add lots of veriety with sticker option so you could
prepare whatever monsters you need, as you need them, and if you can make it so they can be cleanly removed
they could be reusable with a new pack of sticker sheets, and it has the added advantage of taking up less space on a table
and would allow for the use of a smaller grid or map scale, saving table space.
