From the back of volume I:
Vikings & Valkyrs is a role-playing game of the Viking age. It is based on the Old Icelandic sagas and Eddas. The game system is very simple, yet realistic, and stresses role-playing in a low-level context. Moreover, the system has been designed specifically for the sagas. It is not merely a generic system that has been adapted, but an all-new, culture-specific approach.
V&V is the product of eight years graduate level research of Old Icelandic sources. It has undergone several thousand hours playtesting in Canada, Iceland, and on the high seas (would you believe the feryr to Bar Harbour Maine?). It features a chartless combat system that has been played as a game in itself at the University of Manitoba Wargames Club.
If you're interested in the Vikings, role-playing, and the high adventures of the sagas, then V&V could be for you. But be forewarned, the Old Norse world was a tough one. To survive, V&V characters must be even tougher.
