If you don't read it in advance .... why are you generating it in advance?
We make dungeons because we like making dungeons. It give us the feeling that we are in control.
But, if the objective was a to save time, why not generate the next room just before you enter the room? Or, as you need the contents?
I'm not saying fly without a wire but .... really ... that well thought out, meticulously balanced ecosystem of rooms, encounters, regions, and events goes to poop when the first person deviates from the plan.
Why did you bother to write up 100 rooms when ... 3 would do? Filled in with 20 random distractions.
Really, I know our brains hate this ... but ... if you didn't tell anyone, it would be completely indistinguishable from an elaborately "engineered" .... or "designed" or "architected" solution. Trust me, engineering is not about writing 20 random ideas on a piece of paper and call it a plan. (Well ... except ... see the NASA --- don't get me started on PowerPoint.)
Red shows a whole dungeon level on his demonstration and then goes through three rooms and declares it complete. For his purposes that works because he's giving the illusion that there is something in the other areas of utmost importance. Why would one bother to inventory the other areas? (And, he's going to "fiat" them anyway ... so ... even what was written down doesn't matter.)
It's like every Shakespeare play (intellectual, highly regarded) and every 70's SitCom (low brow, sneered upon). Some says "I hate Kale" and someone else hears it as "I hate Dale" ... so a big long plot involving revenge from someone named "Dale" because of a misunderstanding. Shakespeare throws in high falootin words but it's the same thing.
One interesting idea on a note card and the rest could be generated on the fly. (Just don't tell Dale.)
With a little post foreshadowing ... there is no difference.
(As you ponder, erase the 30 years of roll percentiles to see what is in the room ... that's a flawed answer the way it has been done. Challenge your brain to be the dungeon.)
