Well, I'll start then and assume by maps you mean Battle maps? I try to keep a very simple old school style, so that what the players see on the map still leaves much to the imagination while presenting concrete tactical options. It also allows very fast map making through graphic tools (I use Photoshop but I'm guessing other can do it just as well) since it's basically just blue blocks and lines aligned on a grid set to the roll20 proportions (70px). Once done, I export to a simple JPG format, splitting the image up every in 2100px by 2100px if needed for very large maps. Afterwards, I use PNG old school props for rocks, crates, tables, doors, secret doors. Basically anything the PCs can interact with and I end up with stuff like this: LINK (everything but the blue line, which is a cliff, and the background, is individual props and can be used tactically by PCs, moved, destroyed, put on fire, thrown around, whatever!) If you want, you'll find other examples in the session reports here: LINK (as well as a couple of actual maps I use as handouts if that's what you meant) Overall, the idea is: To the point, precise, tactical, light weight, stylish and easy to do. :)
