I don't really use them in 4. I like to do them occasionally if it isn't out of my way or if it fits with the sim/story I have going, but sometimes they just don't make sense. Like roommates who have long term relationships elsewhere wanting to flirt with each other, and neither one is romantic or a serial romantic. Or clicking it away to get the same thing again. A lot of times I feel like mine are pretty trivial and I hardly get anything heavy, like promotions, marriages, etc. The ignorance of any possible bad events and the effects ir would have on a Sim's psyche also annoys me. We get emotions but then they take away wants/fears, which would have worked pretty well together. Sims 2 wants/fears were the bomb. I feel bad always comparing 4 to it because I genuinely enjoy 4...but 2 was just so... great.
