A regular reader sent me a link to what looks like quite a cool game - Subway Scramble where you go "on a rapid transit romp through the epic subway systems of New York, London, Paris, Moscow and Seoul. It's a worldwide wreck of snarled subways, mangled metros and lost passengers. It's up to you to make sure that all the passengers return to their proper destinations! It won't be easy...multiple train cars, overlapping railway lines and a wide array of color-coded destinations make Subway Scramble a unique and mesmerizing challenge."
Sounds like a computer and driver version of the brill London Game - "The object of the (London) game is to visit four of London's places of interest and be the first to return to the main line station from where you set off. You travel by the Underground changing lines exactly as you would in real life".
Like real life there are inevitable hazards like "losing your ticket", "losing your camera", "missing your stop as you're engrossed in a book", "getting stuck in the rush hour" etc etc. Seems like the perfect game to play at Xmas if you're suffering from Tube withdrawal symptoms.
The London Game is currently available from amazon at pretty rock bottom prices, so might make a cheaper alternative to the computerised Subway Scramble!
