Yup! The "multiplayer" layer is more of a lightly connected live feed, so isn't necessary for play. You see ghosts, like in a racing game, which are refreshed from the latest journeys that people have been on. But you don't need to be connected to enjoy the game. Nope. See above - they're more like ghosts. 80 Days is primarily a single player game, but with the ability to be competitive if you wish, and get hints from other players' routes. VERY. You might pass through roughly 20-25 cities on an average trip, and there are 150 in the game. And there's lots of variation within the journeys and cities too.
