Civ6 streamer and history PhD student Paisley_Trees has together with a colleague interviewed Andrew Johnson during the CivGive charity stream last Sunday.
They discuss how they pick the civs in combination with making an interesting and balanced game, that they read the forums here (although that we need to discuss things earlier; although we had the right timing with Georgia), they discuss other leader possibilites in Civ7, and a lot more.
If you are really curious, you have to watch the video and discuss it with us here.
Firaxis has also released a short clip about crises in Civ7. As we know, everyone will at the same time be affected by crises, but they depend on the age, and apparently there will also be some crisis policies with positive impact (although most probably not). Discuss this video with us here.
