I got it a long time ago and didn't really play much, but the whole Cyberpunk ai debacle had me looking up game ai and damn did they really go all out with WD2. Combat is kinda lame, but giving every NPC a little snippet of backstory and having them store emotional state as well as being able to target other npcs really does wonders for creating the illusion of stuff happening outside the player. Most of the time you're just a silent observer witnessing fistfights over traffic and accidents.
