Stellaris

This is a /v/ related article, which we tolerate because it's relevant and/or popular on /tg/... or we just can't be bothered to delete it.

As if creating Crusader Kings, Europa Universalis, Victoria and Hearts of Iron wasn't enough, Paradox Interactive decided that space literally want the limit and so set out to make a 4X game set in the vast reaches of the cosmos. It's notable for /tg/ in that it can be used to fit almost any sci-fi archetype. You want to play as the Imperium of Man and pure all the Xenos for the God-Emperor? You can. You want to play as the Federation and create a noblebright confederation of alien species working together for the greater good? You can. With an insane number of mods available (including explicit 40k based mods) Stellaris is an incredible sandbox for creating grand narratives of the rise and fall of interstellar empires. On the downside the number of paid DLC can be considered almost criminal.
