First, there is no multiplayer so no need to hurry and level up before MP is crowded with upgraded experienced players. Second, there is no multiplayer so you get half of what you got with Unity. Third, there is no multiplayer so you will play this once and probably forget it. Fourth, there is no multiplayer. No hurry so wait for a price drop.
The campaign is good, but I like Brotherhood, and Rogue better, and thought Unity was graphically as good. The issue that set me off on a negative impression was the AI right at the beginning when I was brawling with enemies and onlookers would walk by and not even notice. I dropped barrels and squished enemies and their comrades just carried on with whatever they were doing. Even when noticed by an enemy I was killing his comrades would hardly come to his aid. The game only has a beginner level and there is nothing you can do about it to make this a challenge.
The story is good for video game but like most games the story sucks compared to a good book or movie and takes more time, but if your into the game for the story than you will like this. The controls are good, but the developers should play Infamous to see how much better they could be.
Overall the game is very good like all AC games, so I rate it a 7 (good), would have given it +1 if multiplayer, and +1 for better AI and a higher difficulty rating. It should have been a 9, but I think it was rushed to market without MP and with undeveloped AI.
