Brunelleschi: Age of Architects is a web-based multiplayer strategy game set in the early 1500s, and features innovative gameplay, a player driven economy, and multiple playstyles to suit casual or committed gamers. Brunelleschi will always be free to play, and has no barriers between 'paid' content and free content. The unique 'Sovereign' and 'Minister' mechanics of the game will encourage teamwork not previously seen in this type of city-building game. Complex warfare and diplomacy mechanics will create unlimited replay ability, as will the hundreds of buildings and dozens of districts.
