Sid Meier's Civilization VI: Persia and Macedon Civilization & Scenario Pack Review (ZoDSeR)
In short, you get Cyrus the great who can dominate short term along with long term game and Alexander the brainless who only has short term game if you cannot win game by domination before renaissance era then start a new game because every civ will start snowballing leave you behind so hard that it is not practical to dominate until you got uranium to nuke them. If you play on a map that require ship building research such as continent don't play Alexander he will lose just like play Victoria on Pangea map absolute pointless.
Macedonia got nerf absolutely to the underground that Scythia which is a base game domination civ would dominate Alexander within ancient era without the need of cavalry that is how much nerf Alexander got. Alexander ability is "Do not incur war weariness" and war weariness mechanic got great nerf so great that you will never see a rebellion spawn even when you just straight up purposely kill every single unit of a civ, pillaging every tile along with taking like 80% of their land (practically no mechanic is war weariness so every civ "technically" has this ability). You do not want to own Gathering Storm expansion when posses Alexander because his unique unit is already at trash tier: no CS bonus except when siege (your troop would hardly ever get near city unless that civ is brain death about wall and archer), greater production require and in gathering storm it require strategic resource to built them. Dev also made Alexander have to go to war with another civ to get his civ eureka bonus which is absolute worse compare to before when he also get eureka by dominate free city.
Cyrus the great, however, is what you really want in this pack. He is worth the title "the great" compare to Alexander because his unique unit is SSS tier (It is a combination of swordman and archer which are the two fearsome unit in classical era) not only that he can transition to a long term game with his civ culture bonus while Alexander you cannot. Cyrus the great got unique construction to support his army maintenance later game along with culture and that make him by far a better civ in general.
