I've found that assembling a huge map (battlefield; city; overland trek; megadungeon; castle with grounds) out of, say, 4x4 units tiles, is - like you said - too much. 20x20 tiles even. Takes a lot of work and then there are many-many objects/graphics. But when it comes to the 'premade maps' of 30x30, 31x31, 40x40 units (sizes I have found in Marketplace), it's already a nice size 'encounter map' which some people will use as a single page with just the one map, and if it's made to fit neatly side-by-side with perhaps 4, 9, or 12 of these maps to form a 'huge' landscape, I think this is not too much work for the GM. I do this, and I've seen/played under a few other Roll20 GM's who do this too, but it is typically a more advanced technique or a game that the GM put some work and Marketplace buys to create it. If you would like to come into one of my games that has examples of this, send me a PM, I would welcome you for a chat and actual-use examples. I have some Brass Badger marketplace art in the game, but my 'huge' assembled 12x12's are either homemade Photoshops of mine, or mostly Gabriel's or Hapke's packs from Marketplace, also some Saul Wynne who did quite a few "mega maps" in the Marketplace. My game is just good old AD&D but we try to play it on a fairly epic scale, with a lot of mysterious wilderness, more than a zoomed encounter scale. Saul's Mega-maps like this, look at the Countryside (farmland) ones in this pack, we used 4 or 8 of those Countryside tiles and played for several weeks going across that, <a href="https://marketplace.roll20.net/browse/set/291/map-" rel="nofollow">https://marketplace.roll20.net/browse/set/291/map-</a>... It does seem like the most popular Market option is 5' scale units, for pages of just perhaps 30x30 units, and many 3E, Pathfinder, 4E encounters are written for that size Encounter-Map. Oftentimes a table-mat with markers and minis at home would be around that. But I think there is more of an opening for expanding with more digital GM's to try scales like 200x180 units with either 5', 10', or 20' per unit scales, and allow more of a free-roaming elbow-room (or larger wars, faster vehicles, longer spell ranges). I would say my vote is for 5' per unit, offer 40x40 or 80x80 units per "tile", and allow these tiles to fit together in a 4x6 arrangement, or 9x9 arrangement, or 8x12 arrangement, or something like that. But to really hit a size that hasn't been done as much, it would be neat if you make something like 10' or 20' per unit, provide more than 200x200 units of ground divided into however-many tiles as necessary, that would be turf for something like a car, tank, or war game, or village-to-village overland trek. EDIT / P.S.: Upon reading your Twitter poll I realize your question is specifically towards this Industrial scene. It was tough to vote out of only the 2 choices, since I kind of wanted both, but I voted for the "complete scene" because I feel that is the lesser-served option in the market, and could be useful in Industrial theme for superheroes, tanks, or cars, on that scale. What I'd really like to see is either BOTH in one pack (complete scene, with sub-maps showing detail areas?), or, the 1st option ("Accurate") but enough tiles of this detail that could be arranged side-by-side to make the mega-map (which would look like "Complete Scene" if you zoom out to 10%).
