Venice is an add-on for the latest installment of the Anno (Aka Dawn of Discovery) series, a truly excellent run of the empire building genre.
What makes the series truly great is the balanced learning curve and the simplicity of the interface which underwrites the complicated political and financial interaction. The latest expansion disk adds to the mix the new faction of Venice, new multiplayer modes, new mechanics of subterfuge and economic warfare, and several new scenarios to play through.
The addition of a Base of Operations to your building options now allows the issuing of spies and agents against your neighbouring cities. You can disrupt the economy of your rival, engage in arson, sponsor a false prophet, send a troupe of dancing girls to slow the easily distracted peasants and generally spread civil unrest. This generally weakens your opponents without open hostilities and undermines their settlements, giving you the city elders in your pocket and eventually just buy the Key to the City and take it as your own.
Venice delivers some genuinely excellent features in a game that was already a leader in its genre
