How do you deal with trees on forest maps?
This is one of the issues we set out to solve with Alviss Quest. Below you can see a demo from our Beta where the shadows are cast in a way that the DM never has to draw them or set them up. Trees are actual geometry, so they cast real shadows and block sight automatically; no walls to place, no tiles to swap.
Players can see if they are visible, lightly obscured, or heavily obscured very easily. The world and shadows change, so being a rouge feels more rouge-like. Setting an ambush in the cover of bushes makes sense.
