Kingdom Quest is a browser based social simulation game, fantasy RPG (role-playing), kingdom builder, from Playdemic, free to play on Facebook or Zynga.com.
"Kingdom Quest tells the story of a peaceful Kingdom - famed for its fine foods, crafted goods and impressive markets - thrown into turmoil after an unexpected attack by evil Lord Osric.
The people of the Kingdom are lead to safety by the bravery of the noble King Rowan and his loyal wife, Queen Josslyn. The King was able to lead his people on an arduous journey to the safety of an abandoned Castle many miles away from their now ruined former home.
The castle-folk are tired and their new home has seen better days. Your task is to take on the role as the Royal couple's only child and help build the new home once more into a thriving Kingdom with bustling markets that attract people from all around.
Set in a whimsical world full of medieval and fairy-tale wonder, the castle has to deal with a multitude of setbacks and calamities. If it's not one thing, it's another - one day it's the plague, the next it's dragons. Boils, rats, knights, ogres... it's all going on in Kingdom Quest!"
