How would you add gameplay depth?

Personally I want when a sim gets proposed to I want other Sims like townies clapping and cheering unless their alone also I want the surprise proposal to come back with more options.
I also want to show off ring to everyone and ask parents blessing like in Sims 3 honestly it made it more personal.
Also I want wills like in Sims 2 who gets what or nothing.
Crushes, secret admirer or even stalker love but that's probably a trigger topic.
Slow dance back, Make out like in the Sims 2.
Hopefully we do get a Education School themed pack in the future because that would be grand I still don't care if it's a rabbit hole like in university as long as we can take notes in the class that can help with the homework or test and have other activities.
