Relationships/Generations EP. Add your ideas!

I've been watching a series of videos about things that are in the Sims 2 that aren't in 3 or 4. One of the things that popped up in the video was toddlers fighting over a bottle. I forgot they used to do that and want it back. I basically want back all of the interactions we had in Sims 2 that are missing now. I liked that my kids could dance with their parents, run to greet them when they come home from work and give them a hug, etc. I want my sim parents to give their adult children hugs and act excited to see them. I also want them to send their kids off to college like they used to. My sim went to college, graduated, and is now living with his girlfriend. His family doesn't even act like they're related when he invites them over or goes to visit. I also want my sims to be able to celebrate their engagement with a party where people give them gifts like blenders, toasters, and other small appliances. Their friends and family should react to the engagement in a way that shows how they feel about their relatives partner. I want better dancing options and more stuff for huge weddings and receptions. Sims 2 will be my favorite game forever... unless the Sims 4 team finds a way to recreate that magic by giving the new sims more personality.

Here are the videos I mentioned:
