You might want to check out Terra Invicta. I only played the demo a bit, but it's basically espionage and politics against competing factions to prepare the world for an alien invasion.
The game, while good (i'd rather play Terra invicta than a lot of 4X games right now), feels unfinished and have some part that are either too easy or take too long.
It needs balancing to be clear. But i like that it isn't too micro-intensive.
Vicky3 is my new favorite 4X game now. 3rd playthrough, i really like it.
