This game is a true testament to your own morality... 
Build your small kingdom peacefully without the intervention of others. The centre of culture and science, free from pressures and censorship. Where the weak are not guided by the strong. The true paradise on earth! And then BAM! Kamehameha starts his invasion with his spearmen! Why!? HOW DARE YOU!? I thought we were friends! 

He captures your first city... You, in deep rage, start to build your army from scratch, slowly reclaiming everything you've lost at this point... Finally! We free all of our lands! Should we stop? Kamehameha sends his peace wishes... Oh ♥♥♥♥♥♥♥♥ NO! We will take our revenge!

So we started our own advances on his territory... Taking every one of his cities without much effort... He lost his army at this point. The victory is close... You can sense it! There is still one city left... What do you mean, other leaders denounce us? To hell with them!

You finally conquered his last city! The Polynesia is no more... But what's going on? What do you mean other leaders starting to declare war on us?
You went complete PSYCHO! No one will stand in the way of your justice!

The world war has begun against everyone else. You don't care. You've amassed such a big army at this point, so they don't even look like threats, just mere pests to conquer...
After a long and sluggish war, your enemies are perished... Finally, you can build your paradise without much distraction. World peace is achieved!

Just an outstanding game. The best game in the CIV line, in my opinion. Better than CIV VI, not sure about CIV VII (it ain't out yet). But it has to be something special to beat out this game.

What I like?
-Endless replay-ability. (Tons of unique maps, civilisations, scenarios, DLCs, mods, etc)
-For an old game, still holds good for it's graphics.

What I don't like?
-Nothing to say.

Would recommend.
