I notice there seem to be two primary approaches to playing AD&D.
Those who play as though it is a season of "24" in which every minute of every day is filled with tension, action and intrigue.
the "skip the monotony" folks who will roll for wandering monsters or
encounters on a once an hour or so basis so as to move through the
boring bits quickly and then focus on when something does happen.
I lean more towards "skip the monotony", though I am more of an
increased randomness person.
Instead of just rolling for wandering monsters
once per hour of the day, I have other types of interactions
to fill in the time. So I still roll once an hour for wandering
monsters who I treat as opponents, but I also roll once an hour for
non-opponent encounters, then once an hour for "shit happens" events
like a tire hitting a rock or hole and falling off or a horse breaks a
leg on a hole in the road, etc..
Sometimes I can roll all three
for the hour and still nothing happens. Talk about a boring time.
Eventually though one of the three rolls hits or even all three come up
and then there's more action than anyone wanted.
I've done a
"shit happens" roll where a tire fell off a wagon, a "non opponent"
roll where an elf stopped to ask for directions and a "wandering
monster" roll in which party of orcs attacked all at the same time.
Now things are getting interesting.
