The more boards, especially of a theme (ie. Russia, Italy..) type, are boards that would encourage more design.
Pitman, about a year ago, mentioned that there were no boards that properly represented the small, rambling Russian villages. He was right. That sent me on a tear - sketching dozens of them. Almost all of our boards are designed for European battles - springtime in France. While those type are needed (esp. Normandy), the Russian - and Italian looking village boards (and lets face it - villages are what is most fought over) - would be great new additions to the system.
Having a theme AP, like the one Pete just prepared (AP14) is a great direction forward.
