@italiansarecoming:
Can u Answer about the Prussia thing? Like possibly the decision of making Germany not have historical borders?
Sorry, I thought that was a comment rather than a question. BJCard is right - I can’t comment.
@BJCard:
How often are map changes made during playtesting and how does that happen?
Map changes are much more rare than rules or setup changes. Generally they are very small tweaks that are done to either give one side less of an advantage or avoid an exploitation.
How it happens is that either the designers see a trend in the playtest games that something is either too easy or too hard, or that the game would flow better with certain channels opened or closed. Of course, one or more playtest groups could also suggest a change, which may or may not be implemented. In some cases, the designers will take a playtester suggestion and implement it in a way that makes it even better.
