You should try Civilization V (just make sure to get the Brave New World DLC); Beyond Earth is honestly just an inferior mod of that. I'll grant that they made it a lot more interesting with Rising Tide than it was without it, but RT completely jettisoned any attempt at game balance.
Civ V initially had some balance issues, but with BNW, they've pretty much got it dialed in.
Also, Endless Legend is a recent, OUTSTANDING turn-based 4x. IMHO, it's the best to have been released in years.
Also, the genre isn't a sim, it's called a 4x (Explore, Expand, Exploit, Exterminate), and it's been around for a while: the Civilization series, Master of Orion, Master of Magic, Fallen Empires series, Galactic Civlizations series, Ascendancy, and the Warlock series are all examples of turn-based variants, while Sins of a Solar Empire, Rise of Nations, Sword of the Stars, Rise of Legends, and Imperium Galactica were all real-time versions.

Sims are actually much more tightly focused and tend to be much more in-detail.
