It blew me away when I first put it in, I've made it to the second disc and it's just gotten horribly boring. From what Raype said it gets better later on, I'll just have to slog through til then I suppose.
I forget games come with multiple discs on the 360.
I was pretty bored for a while as well, but I took a rather lengthy break from it (and kept getting distracted by new purchases made in the meantime) and was able to come back to it and finish it up.
