The reactions in Sims 2 were seriously brilliant and so entertaining. All these years later, I can still remember Don flirting with some gal at the H & M store not knowing that a heap of his other romantic interests were shopping there... and suddenly there was a line of females queuing up to slap him. I was laughing my socks off.
As much as I enjoy the Sims 4, the consequences are non-existent and it very much spoils being able to play any misbehaving sims in any way. Romance, kleptomania, evil, mean... all far far too inconsequential and therefore not fun.
