I dont know of an example directly, but hypothetical one to try and show my understanding is random encounter tables.
It could be roll a d100, on 1 to 10 there are different encounters that happen, and 11 to 100 no encounter.
Or it could be, roll a d20, if it is a populated region (see x for what constitutes populated), on 1 to 4 an encounter happens, else 1 to 2.
If an encounter happens, cross reference population density, terrain type, season, time of day and current weather to determine which table to roll on for encounter. If any of above unknown, roll on y tables to determine.
Roll on that given table for encounter.
Now second case for the Sim side of me quite likes, as gives detailed reasons for why get results given.
But may be case that first instance takes half a minute to determine and inform players, while other may take 5 to 10 minutes to inform players. Outcome may even be the same, but even if not, is that time for players essentially doing nothing fair to them for sake of DMs interest?
