Did they add in some story yet. I generally need something other than a free form sandbox to keep my attention in check.
Do these 'campaigns' have an ending?
Well, I pretty much just asked the same question a couple posts back, and Perkel essentially said no.
With a little more research, I've discovered that the new DLC provides a nice focused start to your game. What this should essentially provide you is the momentum needed to go out into the universe, find a faction you'd like to align with, and start doing missions for them. As you progress through your own personal goals, you'll encounter more "story" missions organically as you continuing exploring. So there are things to focus on, but it's not necessarily the overarching "campaign" feeling that both you and I might be looking for. But if you can sustain your interest with sidequests and the like while you pursue your own goals, then it might be worth checking out Cradle of Humanity if you own the base game. With the base game and both the DLC right now, there are a lot more sectors than when it first came out. But again, you're going to have to set your own "endgame" goals if you ever want to feel as though you've "finished" the game. Successfully terra-forming and self-sustaining might be good endgame goals, along with maybe aiding a faction in taking a large chunk of territory.
Anyway, this is again all based on mostly research, and a decent amount of experience with the game pre-DLCs. I have Split Vendetta, and am seriously considering getting Cradle of Humanity so I can start out aligned and guided by a Terran faction.
