I'm enjoying it. You can follow my progress in the "progress" thread within the FFXIII topics. I'm still on my first game (Easy mode), but just beat this bad ass boss who only appears on the bonus 14th day. I ordered the Hard cover guide to use when I start my New Game+ after beating the Easy Mode. That's what I usually do with these FF games; try to get through them completely on my own (with little hints here and there online if I desperately need them), and then buy the book later on when I want to get everything (i.e. go for the Platinum trophy).
