It made dungeoning take less time. If it’s faster, it’s cheaper. Hazing endears the group to the new member. The inconvenience of hiking out to the dungeon after getting a group together, and reforming a group after someone left because the warlock couldn’t summon the tank in time to start the dungeon well before their dinner, was a shared trauma that helped the group cohese.
Old folks talk about how much better life was before tech. But it isn’t just old people. Survivors of war-torn towns and cities also come to look fondly upon their times of utter strife and starvation. The circumstances made every person much less disposable (or less cheap) and so people felt more valued. I remember a news story about someone finding graffiti in a city that was rebuilt after a war, the message translated as “Times were better, when they were worse.”
I did something similar to this but I misremembered the figure. So I got to watch my boss fiddle and fumble for the courage to say ‘actually it was only an X% raise, not Y%’
