It's not a game, it's not a novel, it's both at the same time. But i didn't enjoy playing (or reading) the game cause it was not both at the same time and because the story was not that good neither. If you are looking for that kind of "game" then buy it, if not, move along.
When I was watching a friend playing this game I couldn't understand what he could love in that boring game. But when I put an hand on it, I couldn't stop playing. It's just unbelievable how this game is addictive. Damn, it's already 3... ok one last turn...
