Ubisoft has a thing for open world games, and in this one you get to explore modern day Chicago as a very flawed, hypocritical and ultimately boring
The city is huge, and as expected there are a good number of mini-games to do and skills to unlock while exploring it. Fortunately getting around via train, car or boat is pretty easy once you get the hang of it - complete with a decent enough selection of radio music to listen to while traveling. Another thing to get a hang of is the magical phone which simply gives too much information on the many NPCs. You can turn off the profiler, but most/all the good things only happen when its up.
While it is certainly an entertaining game (and possibly addictive if you like Grand Theft Auto type chaos) there are a number of things that I found annoying. First it's a soft game audio wise, I needed to turn up the volume a bit to hear anything. Also, the protagonist and most of the other characters (specifically those related to him) are morons. I guess it runs in the family? Some tasks fail because you killed the main target, despite killing all his henchmen, some civilians and possibly some police officers in the process, while others it's ok to just go on a killing spree?
Also half the missions are working as the exact type of person the protagonist is supposed to hate (killers), but if you want total completion then... oh well? There's also one part where you run the same map three or so times (because plot device), when really if you just did the "third" time first it would have saved everyone a lot of trouble. At least the difficulty (on Realistic anyway) is good, but there's just something lacking. A likable protagonist maybe? I didn't really give a crap about him or his feelings throughout the entire game.
The game is alright for one ride but pretty much becomes "meh" soon after the first act. I give it two and a half stolen cars out of five. If you want an open world title where you actually care for the protagonist, try Assassin's Creed: Black Flag instead. Edward Kenway is awesome.
