I heard about Agora on the Master Plan podcast, and thought it sounded interesting. You're actually simulating the construction of a society from one of several colonies on a distant planet. It's framed that you're roleplaying the ideologue leader of your faction, but it looks like it's more faction than personally focused. I haven't looked at it too closely, but it reminded me of a Sci-Fi version Dawn of Worlds, although it looks more complicated.
