Rails to the North (2nd Edition)
Depends on your groupMostly positive for repeat players: branchlet auxiliary actions and a fix for end-game station token grabs (BGG 8.6). Some call it fiddly extra, so it suits experienced groups, not a first teach.
Needs: Just the base game
Adds: A board extension with rail paths north and west, branchlets for extra deliveries, reworked town tiles, new player boards and objectives, solo materials and a new cow breed.
Fixes: Gives more delivery choices so you are less likely to be stuck delivering to cities close to Kansas City.
