I definitely would not have predicted this one:
https://www.arahistoryuntold.com/It's being made by Oxide Games, the same company behind
Ashes of the Singularity: Escalation, the massive-scale RTS some folks consider a spiritual successor to the
Supreme Commander series. If memory serves, some of these folks also worked on a couple of the Civilization games back in the day, so I imagine that experience will influence Ara's development in some fashion -- for good or ill.
Of course, all we really have thus far are a description and some visuals. It all sounds/looks good, so fingers crossed the actual gameplay & mechanics are up to the same standard.
What I'm most curious about, however, is whether/when a PC version of the game will be available. The trailer displays the Steam logo right near the end, so that's hopeful, but perhaps Ara is intended to launch on the Xbox first? I guess we'll find out...
