The Road Goes Ever On is a great product for a Loremaster who wants his campaign to range over a large area of Middle-earth. It does differ in several ways from the previous Journeys & Maps for The One Ring. For one thing, the new booklet lacks a section on boats and ships (with expanded rules for river and sea Journeys); perhaps these rules for Adventures in Middle-earth were intended to be included in a future Gondor Region Guide. The previous sections on "Boats and Ships" and "Regional Hazard Episodes" have been replaced with "Events Expanded" (suggestions for expanding on Journey Events), "Encounters on the Road" (rules for NPC encounters), "Dangers Along the Way" (pre-generated enemy troops), "Battle Maps" (a pair of maps for camps along the road), "Avoiding Battle" (an optional system for awarding Experience for avoiding battle) and "Sights None Yet Have Seen" (options for awarding Experience on Journeys).
I was happy to discover that the PDFs for the included maps had been updated from the ones for J&M. Specifically, I see that the Mines of the Dwarves in the southern Blue Mountains are present on the PDFs, where they are missing from the ones for the older set. These maps seem to be otherwise identical to those in the TOR product.
