I think another reason we really need the ability to adjust the frequency of random events is that, currently, their frequency does not scale with length of lifespan.
I play with aging turned off, and also with seasons set to their longest setting. So a sim "year" for me is 112 days. And I play with the same sim for many sim "years". It fact, in most cases, I never age them up at all. And if I do, I base it on the real-life number of years in an average human's lifespan. So my sims can live for thousands of sim days.
My scientist sim has been abducted by aliens at least 4 times so far in about about 80 days. For me, that feels like a lot of abductions, because that's less than three quarters of one of his "years". If I got abducted by aliens 4 times in 9 months, I'd be like... "Maybe I should quit this job and stop contacting aliens." :lol:
But it's an average of one abduction every 20 days. For someone playing with aging set to the short lifespan, that is a huge chunk of a sim's young adult to elder stages, and because it's random, there is a decent chance it won't ever happen before your sim dies. So it feels way too seldom for someone who's playing on short lifespan and actually wants it to happen.
So, not only do I want the ability to change the frequency of events in different saves for different story ideas, I also think this feature is needed so that players can adjust the events to fit the length of their sims' lives.
