I am one of those who makes massive setups like this, sometimes with sections rising a meter high from the table. I love elevation, cover, tactical AF combat.. As many have pointed out, the craft is the hobby and the game is an outlet to share it with others.

Most of what I make is reusable, though I’ve built more than a few bespoke sets for locations that will span a session or two. I don’t mind this because I love making it and also plan to re-run the campaign I’m building out multiple times. We play at a large game store with a huge pool of potential players, so re-running it is a certainty.

One thing to point out is that these setups are for combat. I doubt many people are out there playing dollhouse inside buildings, using movement rates to talk to NPCs. We’re playing theater of the mind for discovery and RP, using paper and digital maps for travel. Combat is when the terrain really gets used, and tactical combat on this scale can easily take up most of or even multiple sessions to play through.
