It might be a failure. It might not live up to potential. All this is a given, especially if they end up cutting corners to get it out in time to be the herald of next-generation awesomeness they're clearly hoping for.
But what I see right now is one of the more effectively cinematic games I've seen in some time, one that creates a genuinely compelling open world that doesn't look like a lot of cut-and-paste sameness filling out spaces between cardboard-box buildings, and one that has the potential to create interesting and dynamic interactions with that world through the hacking mechanic. It looks like it has the possibility of advancing applications of so-called "emergent" gameplay.
Again: I could certainly be wrong. It could be all the cinematic awesomeness is canned non-interactivity. It could be the world is actually as barren and shallow as any number of other open-world games. It could be the hacking mechanic ends up being the same four or five triggers that you can only use in very specific situations, all of which lead to predictable, heavily scripted responses from the world.
But I'm hopeful they'll get it right, and I certainly appreciate the aesthetic they're putting forward.
