If you had an unlimited supply of 3D terrain and props, would you use them?
Do you think the time spent setting up a table is time well spent or that it detracts from the game?
Would it matter if they were physical or virtual?
Maps can be useful for fights, but that depends on system and genre.
For fantasy dungeon crawls, yes, you need maps, and minis of the party are very nice to have. Or, for online, standard sized icons.
For superheroes, I find only Champions/Hero really needs a map, and I don't play Hero any more.
For games like Feng Shui, where the players are supposed to be improvising and coming up with cool action movie stuff, maps would actually be an impediment.
When I ran my D6 pirates game, I put a lot of effort into making maps of the carribbean, and city maps sometimes, but I didn't map out buildings. Action was more cinematic than tactical.
At this point, all my gaming is online, so physical terrain and props would be irrelevant. Once we're out of quarantine, we'll see if the face to face games come back.
