I'm trying to find a good source for elements to generate maps for a cyberpunk game, Shadowrun to be specific, so any modern or near-future map elements (street litter, office equipment, industrial machinery, lots of neon, etc) would be helpful.
Most of the map editing software I've seen, even pricey ones like Campaign Cartographer, produce maps with dated graphics that look like they came from my NES. I want to generate maps with the quality of those found in higher-end gaming supplements, but outside of fantasy settings, maps and map elements of this quality are very difficult to find.
Does anybody have more experience searching for these things that can point me in the right direction?
