I've been using Chicago on and off for a setting since the 2nd edition, and have loved it's rich characters and subplots. The 5th edition version continues this and adds some great layers to an already amazing bit of history. The details about the Lasombra defecton are great, as is the pre made story 'The Sacrifice'. The best thing about this book is that it has masses of great content, even if you have no intention of running a chronicle in Chicago. highly, highly recomended!
[5 of 5 Stars!]
