The expectations of this game are the problem, not the game. Dont expect a GTA clone, Rockstar never said it was so why expect it?
This game has a slower pace, sombre and thoughtful, and that is its strength. It is more like real police work, it is not all car chases and gun fights. It is joining the dots between the clues, using your brain and character judgement. It is very different from anything that has gone before, and that must be applauded.
The absolute stand out feature is the facial animation and the way it is used in game, it has to be seen to really appreciate it (still screen shots dont do it justice). Characters facial twitches and manner can give them away or convince you of their sincerity. It is a stroke of genius really, it is like watching a real person (which you are really, the technology is called performance capture and recreates every nuance of the actors performance).
If you are looking for something intelligent and challenging, unlike anything you have experienced before then check this out. If you are looking for a GTA clone you will be disappointed.
