In Fief: England, you take control of the destiny of a family of lords in a revisited medieval era and try to make them the most powerful in the kingdom. To win, you must make good use of:
your political strength, by building alliances through marriage, giving titles to your lords and ladies, and convening parliament to raise taxes,
your economic strength through income from mills and abbeys, and taxes on towns, and
your military strength, by raising troops (knights, sergeants, archers, crossbowmen) and by making good use of your siege engines (bombards and trebuchets).
Life would be a long, quiet stream if it were not for the calamities that can befall the kingdom:
bad weather that spoils the crops,
famine, which suppresses the income of mills and abbeys and leads to revolts,
the Black Death which decimates your troops and can take the lives of your lords, and
Viking invasions, which destroy cities, castles, abbeys, and other relics if they're not well defended.
All this is now yours to discover...
