Ticket to Ride is one of my new favourite games. It combines three of my favourite things: railways, maps & history. Set in the 'railway mania' era, the object is to complete inter-city routes before your rivals.
I haven't actually got the board game yet, and instead have been playing the iPhone version (which also allows you to compete against computer 'AI' characters, although they're fairly easy to beat). The physical game looks like it'll be even more fun though.
There's plenty of expansions and alternative versions too, which let you play on other maps (the original is set in America), or with additional features (such as ferry routes).
