What does sims 2 have that is lacking in sims 4

Sims 4 is very restricted. In Sims 2, you have more freedom. More creativity and it feels real.
Modding in Sims 2 has less restrictions but in Sims 4, it's almost impossible to mod it past a point.

Cause really, no matter how many mods you add in Sims 4, it still has that dull feeling like nothing matters and everything is plastic.
