The game is in many ways a good stealth games but to me atleast it sadly falls flat of being a good game. I'll do this review in segments and then a summary on my overall thoughts on the game.
My specs are: Intel i7 quad 930 2.80GHZ, 6 GB RAM, win 7 64bit and a Radeon 5870
Graphics: Now the game looks great on the higher-highest settings I played this on the PC and sadly my computer seems to not be up to par for this graphic settings with the game frequently having fps drops and sometimes even freezing. So to get a smooth playthrough I actually had to put the game to low settings and turn off almost all the shadow, anti-aliasing and so on. But the graphics looked nice when I maxed them out to have a look.
Gameplay: I liked the gameplay overall the sneaking around and tools given to you are enough to make it enjoyable but it did'nt feel new or fresh from the old games. The level design is to me the biggest issue here everything is so linear and streamlined there are no real difference to the approach you do during the different chapters and side missions. You can of course chose to go full frontal combat, a mix or ghost but it all comes down to walking through the same passage and overall doing the same thing.
Story: Now the story is linear with no choices at all and the devs have said this is how they want it to give us their story. The only problem here is that the story is not captivating in any way, it was dull, to some part made no sense and the characters that live in the world felt lukewarm at most. The one character I felt was believable was the drag queen courtesan.
AI: Now this is to me one of the if not the most important part of most games especially in a stealth driven game. I might just have been unlucky but in my game the AI was almost down right broken. The guards would quite often get stuck and/or block each other while trying to reach me. A few times while observing the guards if their pathing somehow made them bump into each other one of them would get stuck in their walking animation and then spin around really fast. I can without lying that around every 10th guard would bug in someway. This could include from the above mentioned to something like uttering the same line over and over in quick succession but only saying the first few words and then start over again from the start to simple non working partfinding.
My thoughts: What really annoyed me was something that I at first found as a nice addition this was the way of entering areas by windows. It was a nice addition at first but as after coming to the "sandbox" part of the game a multitude of the buildings had to be entered this way. Now why would this be annoying? Well when you have to do this as many times as I had to do it becomes more of a chore then something enjoyable. For instance in alot of the houses there would only be a few items to loot sometimes as little as a single item mostly giving an average of 10-15 gold so most of the time I would walk up to a window open in look in the room for at most 20-30 seconds and then have to open the window again to get out with the opening and closing of the window taking the same time or longer then the actual exploration of the room. What added frustration here was the fact that once you had cleared out a house/room you had no way of knowing when later on walking through an area if you had looted a place or not since the rooms that you have looted will either not show up on the map or still apear as an unexplored dark area. So the only way to know if you had cleared a place or not would be to walk in again unless you remembered that you had actually cleared it before. Add in the often broken AI, linear and often repetitive gameplay, stale story and I could not find the game to be enjoyable.
