For $60 it's a "on the fence" purchase. Not having Multiplayer and some annoying bugs really hurt the game, and I feel it would be a great/easy sell at $30 or even $40. $60 for this game however screams "buy me because I'm a new flashy game". I found a lot of the cinematics cheesy and cliche. For example, the "DONT BE SAD I LEARNED TO FLY" line was so cringingly cheesy I had to pause and laugh with a friend whom was watching. Other bugs include terrain you could go through, some bugs with stealth, and buggy AI. I've seen the AI get stuck dancing back and forth several times, as well as finding exploits out via the stealth system. If you back into a corner and crouch, guards don't notice you even up-close, at least on the second to hardest difficulty. The objectives could also flash after a while of the player not noticing them. A few times I've had to look really hard in terms of what I should be doing; it would have been nice for the game to just point it out to the player after a few minutes of being lost on objectives, or atleast replay the audio directions for the objectives. Luckily I had a friend over and most of the time we'd figure it out together (almost always was cutting chains that I'd miss).
Another thing that is mildly annoying is how erratic the game plays at times. When I first started I had the game dialed in for my rig and above 60 fps. By the third level I had to lower settings as randomly it would start chugging, sometimes fixing itself when I'd reload the graphics settings. For reference, I use 16gb DDR3 1600, I7 2600k@ 4.4ghz, and a GTX 580 OC'd on water.
TLDR: Buy it for $30-40, or play it via sharing on steam. I personally don't think the game is worth $60. Single player only, slightly cheesy "already been done before" shooter.
Things I liked: Knife kill animations, the whole level scares like giant robotic dogs biting at you as you round corners, etc. It's like someone mentioned above: you can feel the dishonored stylings throughout the game, such as the large focus on stealth. I did entire levels in stealth.
