The problem with Pandemic that nobody talks about
Brass Birmingham's end-game scoring calculation is often closer than players expect because both network links and buildings score separately. Players who focus exclusively on building quality sometimes undervalue the network link scoring that comes from connecting cities. A comprehensive railway network scores link points separately from the goods scoring that buildings provide.
The asymmetric scoring between canal and railway eras creates a scoring structure that rewards different activities in each era. Canal-era cotton mills score for their production. Railway-era merchant access scores for goods delivered. Understanding which scoring system rewards which activities in each era shapes the investment decisions within each era.
For Birmingham players who feel they do not understand the scoring: calculate it explicitly after each of your first five games. Identify which sources scored most, which scored least, and where you could have done better. The post-game analysis is one of Brass Birmingham's best features.
