Pros
Pro Game content
It's huge and allows for massive replayability, it has many historic civilizations like Rome, Mongols, Spain, India, etc and it has many buildings and units and many more mechanics like religion and city states , and its still awaiting many major updates to things like espionage and tourism.
Cons
Con Very basic graphics
All in 2D and trimmed down to a minimum, not for fans of HD graphics.
Con Lack of event information
This game has notifications to tell you about game event, like production, city growth, or battle event. But this game is not telling you, how your unit got killed, who is killing your unit (if they have same unit type), and lack movement info.
Most of the time you will miss important things because, you don't know what actually the enemy or ai does.

Pro Completely free
As Unciv is an FOSS game, not only is it free to download, but it does not have any in-game purchases.
