Sims 4 Countdown to Doomsday Challenge

I've missed the Doomsday Challenges since Sims 4. MistyDW makes my favorite challenges, and I'm glad to see a Sims 4 version of the Doomsday Challenge! Although I'm sure it will be tons easier in many ways, b/c Sims 4 is like that; I expect I'll enjoy this. It's a good way to avoid finding CC for my History Challenge's next Era.

I'm wondering, do you plan to do all of the sequels or just the Colony Challenge?
