I'm really surprised no one mentioned Terra Invicta!
Basically if the Three Body Problem series was a Grand strategy game.
In terms of grand strategy it is quite grand. So massive and complex that even 100 hours in, I haven't completed a game.
That being said, it's so addicting. I haven't really played any other Sci-Fi games where you can take over multiple countries on Earth, take over other bodies in the solar system, and field space Navy to defend the planet.
Praise the code! 🤘
