The Sims Summit

Not that long after Firaxis released Civ 6, they had a livestream where they presented a multi-month roadmap called the New Frontier Pass. This included specific game features that were coming, along with 6 future DLC packs. They stayed quiet about the cultures and leaders they were introducing - it was a good way to build hype. The devs stuck to their roadmap really well, and it was great to get something new to muck about with every other month.
I'm hoping that as an EA stable mate, the devs behind the Sims take a leaf out of Firaxis' book. It was a good time to be a Civ player.
