I've had my eye on the DLC for This War of Mine entitled The Little One's for quite some time now. I've put in some 50 or 60 hours into the base game, and found it a very solid experience I keep returning to play.
The DLC is presented as an expansion, with the main draw being children added to your list of survivors. From what I can tell you can't actually control them on scavenging runs, but rather you must take care of them in your base. They require a completely different set of factors to be happy, and must be protected. A sensitive subject to be sure, but one I'm confident the developers handled with finesse, much like the original game.
