The Sims Medieval is a life simulation game that was released in March 2011 by Electronic Arts for Microsoft Windows and Mac OS X and on September 22 2011 for iOS as part of The Sims series. It was also made available for Windows Phone on March 26 2013. Set in medieval times it allows the player to build a kingdom through quest-driven gameplay. During presentation at E3 2010 a pre-order exclusive Limited Edition was also available. The Sims Medieval is a life-simulation game with action-adventure elements having a more role-playing video game tone than past Sims games. The storyline of the game is to build a successful kingdom by fulfilling the player's "Kingdom Ambition" which the player chooses at the start of the game. Once an ambition has been completed the play will unlock new ambitions for future playthroughs as well as unlocking freeplay for that specific kingdom. The major difference in the gameplay is that the game is quest-driven. With the game stopped the player has to choose a quest (quests are required to fulfill said kingdom ambition) and then choose which hero Sim they want to use. A player can create Hero Sims to control each one having a profession (monarch knight merchant and the like). The character creation simulation and architectural aspects are significantly reduced and altered to enforce a sharper focus on role-playing-style gameplay. For example players are able to customize the aesthetics and layout of building interiors but unable to alter the basic structure and shape of buildings.
