Age of Empires 4 DLC has been pretty hit-and-miss over the years. The Sultans Ascend, despite being the oldest of the three currently available expansions, is by far the strongest, bringing with it a new campaign and entirely new civilizations. Since then, co-developers Relic Entertainment and World's Edge have mainly defaulted to repackaging existing civs, releasing variants that have left many less than pleased. AoE 4's latest content drop, Yue Fei's Legacy, launches today, and it brings with it a brand new civ, the Jin Dynasty, and a full-fledged campaign that'll help you get to know them a little better. From what I've played so far, the studios' execution across the board makes it well worth dipping into your gold coffers for.
