This definitely isn’t the best BioShock in terms of gameplay, but it’s so beautiful and detailed that I don’t really feel like criticizing it. Besides, there’s a wonderfully tangled plot! And Elizabeth :-) David Brown has already said it all in his “Limelight”; I have nothing to add.
I’ll definitely play it again, just to look at everything once more. I’m not sure how I’ll approach the DLC, though: to me, the story of Columbia and its children is as complete as a story can possibly be.
