Hi, at a local thrift shop, I found some pieces that would make decent cliff faces, ones that are roughly 6" high and 18" wide. I might build some narrow escarpments on top, and use them to line a table edge, but how useful would they be in gaming?
Although the Incas had ambushed Conquistadors in canyons, and the film Warriors of the Rainbow: Seediq Bale reveals other, similar possibilities, how else might cliffs feature in a game? Even at some less-than-vertical slope, figures can't easily be placed partway up without ledges. Is that the whole point - impassable obstacles which must be surmounted elsewhere, e.g. up ravines?
