The premise is basically the same- you sneak around, kill some people, but try not to. Yet they feel as different as cutting open a box with an exacto knife vs. trying to stab an avocado without holding it. One is precise and surgical, while the other flails about. It works for each in their own way, one being set in a gorgeous futuristic setting (even when it’s supposed to be dirty), and the other looking like the scenery is decaying as you play.
