Family gathered at a stream in the Hinterlands; famous for having a fire in the water. More folks found after the towers are constructed. Others at the Crossroads; merchants, guardsmen, etc. Now I do not pretend to recall what all were doing, but I seem to remember that none were as static as in DA2 for some reason.
Ignore content if you wish; still is there.
Let´s say, for the sake of the argument, that DAI has lots of life, activity and animals;
The Witcher 3 not only have more, but they are better placed and distributed, because I do remember much more the mundane activity in TW 3. The world in TW3 is way more alive, from the lines to enter the blockaded villages, to the large settlements - and if you stop to overhear people, you can get hints for quests.
I am not even going into the merit of which world is better, but TW 3 is way more realistic. More animals and more people in larger areas doing all kinds of different things: eating, guarding, sleeping, working, walking, waiting, arguing, gossiping, cleaning, playing cards, dating, kids running around and so on.
DAI has some of this stuff sprinkled here and there but it really is not on the same level.
