XCOM Long War mod creators are making their own 4X strategy game
Pavonis Interactive, the same team that made the Long War and Long War 2 mods for both XCOM and XCOM 2 respectively, is developing a grand strategy game called Terra Invicta, which you can back now on Kickstarter.
Chances are that if you had any passing interest in modding Firaxis's excellent turn-based strategy games, you'll have heard of Long War. They're widely celebrated mods because they both meaningfully expand on what makes both XCOM and XCOM 2 so intense to play, while also giving you new gameplay mechanics and toys to blast away the alien scum.
Terra Invicta is described in the Kickstarter post as "a grand strategy alien invasion game". Nothing wrong with sticking to what you know works, and it seems that you'll be taking on the role of one of several human factions looking to dismantle the aliens' invasion plans in the title. Since none of the factions can agree on the best strategy to rid Earth's colonies of the alien incursion, each of the available factions have their own agenda and goals.
