On the Underground is a rail-building and passenger-moving game that first appeared in 2006 from JKLM Games and Rio Grande Games, and the newly titled On the Underground: London/Berlin features the same gameplay, with some modifications to a London map and other small changes.
On a turn, you can take up to four actions, with those actions being building track or taking branch tokens. Each player has 2-4 colors of track depending on the player count, and normally you can extend a colored line only at the endpoints; if you spend two branch tokens, you can branch off an existing line. After you build, a passenger token moves to one or two stations following particular movement rules, scoring points for those who own the tracks upon which it moves. You know which stations are in play at the start of your turn, so to score points you're both building for those immediate passenger points and trying to connect to particular stations or build loops
• Another title being brought back to market in a new edition is Klaus Teuber's The Starfarers of Catan, a giant space-based take on (what was then called) The Settlers of Catan that was as famous for its rocket-shaped randomizer as it was for the tendency of parts of that rocket to break off.
In Q4 2019, for the twentieth anniversary of The Starfarers of Catan, German publisher KOSMOS and the U.S.-based Catan Studio will release Catan: Starfarers. This new edition of the game features completely revised graphics and game materials — complete with redesigned mothership pieces! — revised rules, and a variable game board that brings even more variety to your spacefaring expeditions. Catan Studio plans to demo Catan: Starfarers at Gen Con 2019 in August ahead of the game's Q4 2019 release date.
