I found this source book was really useful. It's versatile and detailed with a lot of encounters and adventure hooks that you can either use in the campaign provided by the book or pull out to use somewhere else. The Ancient Greece theme was really fleshed out and would be great for using in that setting, but you could also re-theme a lot of it to your own setting and still have it work great. I especially liked the Cave of the Tables of Knowledge as a really cool mini dungeon that I plan on using for my next game.

A really clever, inspiring idea, but a lackluster implementation.

A book trying to serve multiple goals: fantasy fiction, campaign inspiration / example, an actual setting. It certainly doesn't seem to really address the first goal; it's adequate for the second, but not useful; and as for the third, as one might expect, it's quite dependent on real-world Greece, with a bit of the authors' Swords of Kos setting for flavour.

The entire book has a grey backround image behind the text on every page; coupled with long passages in italic font this makes for difficult reading. It's an inexplicably poor choice to make a book that's not meant to be read? There's padding, repetition, and leaden writing in places; it looks like the author has an outline for "information I need for every settlement", filled that in, then tried to directly convert to prose; the result is not as usable as a bullet list or outline would be, but has all the plodding prosody and interest of a teenager's mechanical essay-writing.

I want to use something like this idea of a pilgrimage route in one of the 5e greek settings (Theros / Arkadia) and will update this review with notes if I can pull it off; it'd be a neat way to add a bit of sandbox and worldbuilding around some of the adventure paths that have been published for them. It also makes me think it'd be awesome to work on something resembling one of the medieval Christian pilgrimages - Campostela or Canterbury, perhaps. Is there something that would fit for Beowulf? In any case, it's going to take careful work to adapt to whatever game world society/theology one is working with.

A Travelogue with adventure hooks, terrific detail and narration. I had never thought of a pilgrimage as a campaign, but this book puts it all there for you, as well as open ended to add your own, including, but nor limited to olympic level competition, mysteries, votive acts, and like any vacation, souvenirs. Reading this would make anyone want to travel the real life journey in present day Greece, but for the moment I'll just roll up my own demi-god.
