Sims having five traits instead of a measily three, and them doing a lot more too to give them personality. This from Sims 3.
More animations too, replaying Sims 2 especially makes it painful how few animations Sims 4 has in comparison.
And from Sims 1, clown catchers and the sad clown being this otherworldly menace again. Many of the sims 1 surreal and chaotic moments should make a return really.
Sure cars, drums, elevators, time travel, more occults and such would be neat. But it won't matter much if the sims 4 still remains so boring at the core.
