I'm not saying anything new, but this is how not to modernize a series. The worst part about it is, that you do sometimes get close to that Thief feeling and imagine what could have been, but then it's gone.
This blew everyone away back in 2004, and you know what ? It's still good! The highlight for me was the cryo-sleep pod section. Absolutely terrifying if you think about it.
This is why you don't discuss art with binary definitions. The story is a mess with some good parts. The gameplay is tedious Bioshock shooting, but still playable. The art design is fantastic, and so on.
For stealth freaks only. Expectations were low, but was pleasantly surprised. They even pulled off having half of the game be backtracking. The story was better than expected also.
