Would be happy to answer that. Alright, first, you are 100% correct. It is almost certainly subjective. However, I've seen enough of this game to know that it's already more interesting, ambitious, and refreshing a release than a lot of what has already been released on these new consoles. I've seen a lot of things that I really like about this game that make it feel like a pretty unique entry into an ever growing field of open world titles. When people either screw around or just don't know what they're doing, this game can look a bit off putting, but when they play it right or the player is damn good, and they carefully take advantage of the possibilities, this game looks downright amazing.
I love how the player can interact with the world around them, and influence and affect enemies and other NPCs in all these cool and interesting ways. This game is just amazing cool as a concept, but what I love most is that it appears ubisoft, albeit with some blemishes here and there, have succeeded to a strong degree. I have not allowed the craziness (more like silliness) about graphical downgrades or lighting changes to distract me away from the fact that the game I saw back at E3 2012 is still very much here, and appears even more ambitious than what that E3 2012 video ever showed.
What they're trying to do with this game isn't an easy thing, and maybe I'm cutting them a little too much slack, but I tend to reward devs that take real creative risks with an optimistic outlook until I get to play it myself.
