here’s a bunch of weirdly in depth d&d questions i have that’s going to take me years of experience to answer so it’d be helpful if someone knows any of this already: so when gygax says, pretty much constantly, that keeping track of in universe time is essential to dungeon crawl campaigns,

1) does this still hold up as true? is there really no way to wing it that DMs have found in the last 30 years?

2) does it still hold up if you abandon wandering monsters for a dungeon with only keyed encounters?

3) what’s the easiest way to count time at the table? should i get an abacus or an app or something like that to calculate time spent?
