If I would feel generous, I would say that it's a watered Thief 3, but it's not even that. The AAA production that tries to be Thief but it fails. Even Dishonored felt to me better in stealth department. The tools of course are locked and you have to move onward with the story to have the whole set, to finally start venturing through city, which feels really claustrophobic. The developers have implemented a lot of ventilation shafts, like I was in some Batman rip-off. Of course those paths were mostly the most optimal. There is also Focus, which is basically Bat vision, and we are forced to use if we want to save a lot of time. The city felt to me like Arkham City, more oriented in vertical availability to omit the danger, than to go on the ground to find your next objective.
The side missions, while interesting, are even smaller and can be finished in 5 to 10 minutes at best. For the most of the game I used only water arrows and didn't have had to buy anything anyway. If you really need something, it will be included on the new map. What is "amazing", that this is a stealth game without the ability to jump. Garret is like a Doom space marine now. All actions are context-only - you can traverse, mantle, hide behind or climb only the entities marked by designers. I forgot about the rope arrows. They can be shot only at special rope-wrapped logs sticking out of certain buildings and ancient caves. Just so you don't get confused, trying to break the path or something. Also, there are immersive interaction sequences. Everything you grab or do is being animated. This gets old rather quick, when every penny is being taken like a jewel of ancient Nile. The guards haven't impressed me. If you finished earlier titles, they will not create big problems. Usually the developers went for bigger numbers, when they felt that they need to make it more difficult.
The story is a mess, and the writers didn't knew in what direction go. Sometimes it's dark, sometimes edgy, humorous and with some extra AAA bombastic moments. There are some little details to original trilogy, but everything felt to me more plain and normal, like a strange Victorian setting that is really forgettable. You can finish everything once, and there is nothing that could encourage you to replay it.
I finished it once before retiring my good old Athlon 64 X2 4600+ 2,4GHz rig this year, and the optimization was the best thing about it.
