I still can’t believe no one has made Alpha Centauri into a sci-fi Game of Thrones. The story and plot are great.
The big problem is that Electronic Arts owns the rights to SMAC, and they're not interested in doing anything with the intellectual property.
There's Pandora that is a much better attempt than Firaxis' Beyound Earth, but if I may suggest, you shouldn't expect lightning to strike the same spot twice.
You can however hope that, just like with Civ1 (=> Civ2) => SMAC(X), someone will be inspired enough to take some of the best aspects of it in a somewhat different game :
