Played the game for some time now and am close to the end and overall my impression is this is a cheaper version of the Batman Arkham game series. Graphics are nice and the game does not slow down when the highest settings are set, unlike Watch_Dogs. After awhile the game becomes tedious and the controls from the keyboard do not always work as they should and in some cases I had to start missions over because Talion performed differently then what was expected. In some cases it could be user error but other times he just did not do the task requested.
I will admit I am more of a RPG player than an adventure game player and though they are similar there are some differences, in my opinion, and that may affect my grading but I did give Arkham City a 9+ grade so if a game is enjoyable and yet challenging, has a good storyline, presentable graphics (though I do get sucked into graphics that are more detailed), and plays well, then I do grade it up.
