What does sims 2 have that is lacking in sims 4

Yeah I haven't played The Sims 2 in a while since you know it is just a bit old especially when you have been playing it for 10 years but I remember having a lot of trouble trying to figure out few things like where to find secret lots, treasures, how to get into private school. There were even things I didn't know existed, not gonna say what but sometimes with The Sims 2 you really need to keep an eye open for the most crazy things.
