where is the first assassin's creed based
The first Assassin's Creed introduced core elements that remained in the rest of the game series. The game creates fictionalized, historical versions of Masyaf (the Brotherhood's location), Jerusalem, Acre and Damascus, and incorporates a number of documented historical figures into the story. Other core elements include the virtualized Animus system, free running, climbing, stealth, parkour, and the initial formulation of the combat system. The game requires the player to complete a number of side quests before they are able to obtain an assassin quest from a local Brotherhood guidemaster in each city, but this side quest prerequisite was abandoned in future games.
