Expeditions: Viking - Interview @ GameInformer

GameInformer has talked to Jonas Wæver, the creative director of Logic Artists about this game. Here's a bit about the inspiration:

Wæver says there are benefits and challenges to working in this time period. "The Viking age is both really easy and really challenging to deal with historically because written accounts are so sparse and so biased - the Norse didn't really write a whole lot, since brevity is of the essence when you have to chisel your words into stones!" he says. "This gives us a lot of freedom to choose our own approach to the historical elements, but it also makes it difficult to find trustworthy sources to rely on for shaping our game world. Fortunately there are tons and tons of archaeological sources about the Viking age, so we've been relying on a lot of that to get the clothing, the architecture, the tools and weapons, and the ships just right."

In addition, the Danish main television station, DR, also has talked to Jonas Wæver.
It is in Danish, so here's the link to a google english transition of the Danish interview.
Here's a bit about how the company has reacted to the criticism of the first game, Expeditions: Conquistador:

The game was at home criticized for bringing a traditionally colonialist worldview of the Spanish conquerors, and in Latin America came the criticism that the game was racist in its depiction of the native Indians. For Jonas Wæver is what some were interpreted as being politically incorrect, the price of the game could be historically accurate. - But we listen very carefully to the criticism, because we would not want to be guilty of distortion of history, emphasizing Wæver who are curious to see if the 'Viking', who also slaves, they cause just as much criticism and indignation when it is released later in the year.
