The Ruleset and Network of the new Lea Hall ruleset are interesting and varied from Mornington Crescent. The situation of the stations, and the slightly larger scale means that it is a perfect network i.e there are no permanent loops and pitfalls. Although this sounds boring at first, play can become more competitive as a rule was added to make the creation of temporary vortices easier. Thus, if you wanted to really drop your opponents in it in an All-In game, a temporary vortex could be created anywhere on the network via the Anderton Vortex Law. It would be difficult to explain the entire ruleset here, but there are many little intricacies that should make the game quite different from the traditional Chalk Farm '84 played on a different network that we see so often these days. I suggest you all take a read, available from [IMCS], your local MCC or a good bookshop!
