The future of sims 4

I have been playing sims since it was sims 2 and I was watching over my sisters shoulder. I am a huge fan of the game and have loved seeing it develop. However my sister mentioned today something I agree with and that I think could feature in the future of sims. She said that the experience today is vastly different from sims 2, and that it doesn't feel like sims anymore. I agree, it's changed a lot. From things like the simple way the face physically moved when changing it to the game play, it's different, as is the nature with development. But as a dedicated sims 2 player she has always said she doesn't feel taken by sims 4 which is a shame because I know she loved it. This brings me onto the future of sims 4. Recently I heard that the development of a sims 5 had been benched, which I was relieved to hear because I really don't want to have to buy a new bade game and expansions all over again. But that leaves the question of what meaningful changes can they bring to the game in the future, aside from online co-player features there's not much. I think they could pull back in a large group of ex-players by creating a sims 2 and sims 3 expansion pack for the sims 4. This would, while keeping all that new stuff like animation quality etc, bring back a few of the nostalgic game play aspects that old players used to love. This would be optional of course as is the nature with expansion packs and they would obviously have to work with the game and all other content,but I think brainstorming something around this could be a great rout forward for sims. By appreciating what they had in the past and bringing those left behind players into the now and creating a space for them.
