I will admit, the first 2 1/2 chapters were pretty dry and full of tutorial material. It was almost a turnoff for me. But after all the cruel and unusual punishment, it opens up and feels more 'fresh'.
The story seemed half-a//ed at first, but the more you progress, the more you'll appreciate it. In my opinion, it was actually well-made with minimal plotholes (compared to other games of it's genre...i'm looking at you 'Killer Is Dead'.) and gets you thinking outside the box with it's take on what type of future may come of social networking. (PS: Storywise, the chapter intermissions were my favorite. They were dark, yet philosophical.)
The combat system is "blargh" at first (that's the only word I can describe it with), but the more options you open up, the more fun you have with it. Also, you'll be running into new types of enemies throughout the entire game, so you'll have to switch up how you fight in order progress, which keeps things 'fresh' enough until the end of the game.
The boss battles are all around great. It's probably the most fun this game has to offer. I won't describe those. Reading details off of an online review does no justification.
I honestly give this game a 7.5 ('8' rounded up), since I had a good experience with it, but overall, the beginning could have been better. As for the ending: it was worth it.
--And for the books, this was a GREAT weekend rental, but I do not advise buying it. The replayability dies once the credits finish.--
