1st post, but long time lurker here. The past couple of days, I've been rolling with Cyrus and loving the early war bonuses (especially the +2 movement). I'll usually war out my neighbors into the medieval era with archers/warriors(+immortals)/horsemen taking out 1-3 other civs. I'll find myself with quite a bit of free land and bad/lackluster AI cities. I feel Persia's Pairidaeza (Persian garden) transforms lackluster locations into fields of gold/culture. Built on grassland, plains, or desert (including hills) +1 Culture (+1 with Diplomatic Service, +1 for each adjacent Holy Site and Theater Square) +1 Gold (+1 adjacent to City Center and Commercial Hub) +2 Appeal to surrounding Hexes All culture on improvement yields Tourism (1:1 with Flight) It's flexible as well as consistent which sets it apart from other unique improvements as it benefits from districts instead of lucky resources/wonders. The +2 appeal stacks with each other and can make adjacent seaside resorts and national parks yield much more tourism in later eras. Gardening out these sub-par cities involves stagnating their growth by forcing the population to work the Pairidaeza and should only be used on poor terrain, small, and/or conquered AI cities that would/could otherwise be razed. Cities with good hexes/locations etc. need not apply for pruning. Alternatively, a player in later eras (industrial-future) could produce some settlers to take advantage of Pairidaeza's appeal bonuses toward seaside resorts. The city doesn't even need to complete a holy site/theater/commerce hub for the Pairidaeza's adjacent bonus to kick in. Just place and increase yields. Overall the Pairidaeza feels like gold/culture puppets from Civ 5. Persia's domination victory is readily apparent, but I'm sure it may have a good shot with culture.
