Holy thread necromancy!
First off, welcome to ENWorld, [MENTION=6788747]Askalon1510[/MENTION]! I'm glad to hear 5th Edition is bringing you back to gaming, and has your family into it too. Some of my fondest memories are gaming with my brothers when we were young(ish).
Secondly, I think we can now see the shape of 'Living Campaigns' in 5th. Encounters programs have a persistent story, letting you gain rep with factions and influence the shape of the narrative in big convention events. What I've seen, and what I've played has all been quite good.
