the game's rating, I feel, is too high for various reasons. There are plenty of reviews about the game's merits, so I am only going to talk about the bad things. The review of gamespot actually talks about the bad aspects but these would not be fully appreciated until you play it
1. stealth is too easy
as long as you are in the shadow, stealth is too damn easy. Cannot be compared to dishonored, whose stealth is so complex and intriguing.
2. shooting mechanics are out of date
3. graphics needs a lot of improvements
