I grew up somewhere that had all four seasons. I now live somewhere that the seasons are basically, to me, 'early spring, late spring, early summer' and that's it. And I really miss the seasons I no longer get to experience. I don't want my Sims living in the same sort of conditions!
More seriously, though, I like the tiny bit of unpredictability from day to day, and it also gives me a much better sense of time actually passing. I also just ... like how it looks, and it encourages me to actually use holiday-type stuff to decorate once in a while. Seasons is always the EP that makes me feel like 'okay, now I have everything to make the world feel like an actual place.'
