The game its pretty much more of a cinematic presentation than an actual game. Long cut scenes and dialogue that you have to watch and listen to. Then you have a bit of walking around to do (it tells you where you need to go) you can't go anywhere and interact as and when you want. Then there a bit of fighting involved, similar to assassins creed but not nearly as well done. Then once that's over its on to another dramatic cut scene to watch, its that kind of thing.
There obviously more time and effort gone into the presentation than the actual gameplay, I wouldn't necessarily say its a bad game, just nowhere near as good as all the hype made it out to be, and, like I said before, once the story has been told and you've completed it, there's not much else to do.
