I can't speak for the Ardenne region. But in Brabant, Limburg, and Gelderland all of which feature in either MG or FB a large number of churches are constructed from red brick, and differ greatly in design from Norman churches. But that would have meant even more work for BFC. Also, I would have liked to have seen Belgian, Dutch and German post boxes rather than the "RF Postes" that we had in CMBN, but it's not a game breaker.
