High Street with it's paved roads and fancy buildings is a Rank 2 Commerce District and the first commercial district a Sovereign gains access to. One might think it less focused in purpose than perhaps the Residential or Mines until you consider the purpose of providing citizens with the pursuit of happiness in the form of purchasing things
District Action - Work in Shop
All it takes is a few Action points and a solid work ethic to stand behind a counter and make correct change. Okay, so maybe it also takes a pair of legs and some arithmetic ability as well. Either way, with a High Street there are shops to work at and jobs for those who would like to do so. While some may do it just for the fun, most will do it for the salary. Working in the Shop provides players with a somewhat random equipment reward and some Silver Drachmas.
Main Building - General Store
The General Store is a Rank 2 Crafting building as well as the Main building of the High Street. Like most centers of commerce, this building raises Prosperity (+1/lvl Settlement wide) and lowers Security (-2/lvl within the High Street). The General Stores crafts Accessories and assembles crews for new Carts. As it's final beneficial effect, it reduces all Groceries costs in the Settlement by % per level.
Exclusive Building - Pub
Linked Building - Grocer
Minister - Burgomeister
Downsides - Unsafe!
When one imagines a bustling shopping district, safety is not the first thing that comes to mind. In fact, most canny shoppers already hide their currency somewhere that is neither obvious nor easy to get to. The more foot traffic, the more chance at petty crime. While murder is unlikely in a healthy High Street, crime becomes a serious possibility if not curtailed by a canny Minister and careful Guardhouse placement.
