Well, if it's WWII in the trailer, wouldn't Queen Wilhelmina be the ruler? Or, according to Wikipedia, one of the prime ministers called Dirk Jan de Geer or Pieter Sjoerds Gerbrandy?
And people dare complain about Tribhuwannottunggadewi Jayawishnuwardhani.... The Dutch seem not that different : P
I just read this on Wikipedia about Queen Wilhelmina, and it actually makes her as a possible candidate for The Netherlands. I don't know all that much about her, but this segment could be tweaked to warrant some gameplay elements
Wilhelmina was well aware what was expected of her by the Dutch people and their elected representatives. At the same time, she was a strong-willed and forceful personality who spoke and acted her mind. These qualities showed up early in her reign when, at the age of 20, Queen Wilhelmina ordered a Dutch warship, HNLMS Gelderland, to South Africa to evacuate Paul Kruger, the embattled President of the Transvaal.
Wilhelmina had a stern dislike of the United Kingdom partly as a result of the annexation of the republics of Transvaal and Orange Free State in the Boer War. The Boers were descendants of early Dutch colonists, to whom Wilhelmina and the people of the Netherlands felt very closely linked. In conversation with her former governess Elisabeth Saxton Winter, she once teasingly referred to the Boer soldiers as "excellent shots". She was not amused to hear that a Dutch medical relief team was planning to accommodate the needs of both Boer and British wounded soldiers.[6] Nevertheless, in 1940, King George VI sent the warship HMS Hereward, to rescue Wilhelmina, her family and her Government and bring them to safety to the United Kingdom, which offered the Netherlands facilities including broadcasting time on the BBC.
Queen Wilhelmina also had a keen understanding of business matters and her investments made her the world's richest woman, as well as the world's first female billionaire (in United States dollars).
Before the First World War started, the young Wilhelmina visited the powerful German Emperor Wilhelm II. The Emperor thought he could impress the queen of a relatively small country by telling her, "My guards are seven feet tall and yours are only shoulder-high to them." Wilhelmina smiled politely and replied, "Quite true, Your Majesty, your guards are seven feet tall. But when we open our dikes, the water is ten feet deep!"
In relation to a new board game (Pandemic Rising Tide) I read up on the Hollandsche Waterlinie (pardon my spelling if it's wrong) and that could be a very interesting gameplay mechanic. It allowed the Dutch to flood parts of their country to stop invaders.
