Publishers, take notes.
THIS is how you make a DLC.
Solid base game, yet add this on you become so accustomed to its changes the base game feels ♥♥♥♥ without it.
-Caravans and Cargo Ships are the bomb
. You finally have a way to keep a decent sized army and supply for it
-The new civs are fantastic and fun to play
-Ideologies can be annoying but in a good way.
Your best bud from 3000BC now hates you because he's a fascist and you're a fat cat capitalist; and now you're making an alliance with some dude who hated you a long time ago. It basically makes the late game more interesting by adding policies that are great and breaking long time friendships while forming unlikely allies
-The new culture victory is so much better
than the old one; you have to think more than 'THIS IS CULTURE I WANT BIG NUMBER'
but also changes the three great creatives to be useful to civ's not going for a Tourism victory(except for one. Im looking at you, great musician.)
Probably a lot of stuff I missed but who cares, this expansion is the best one i've ever played. Like I summed it up at the top, this is what DLC should be and it was well worth my 12 pounds.TL;DR : Dont like base civ 5 as it feels empty? Buy this adds insane depth and great mechanics. Like Civ 5? Buy this, it adds on to the game so much.
