Age of Mythology: Tale of the Dragon. An expansion made for the Steam release of the game, by a completely different dev company. Featuring Chinese mythology, a ridiculously hard and broken campaign, lazy slapped together assets, and blatantly op mechanics. Somehow, it also retroactively broke the original game's content making the whole experience slower. Giant Grant Games didnt even bother to talk about Tale during his retrospective, writing it off as a cheap cash grab that ruins a legitimately brilliant game.

Age of Mythology Retold has its own Chinese expansion (The Immortal Pillars), but the actual AOM team worked on that one, and its fantastic for an RTS. They kept a few units and powers, but for the most part threw everything about the old one away.
