To recap, in 2016 Z-Man Games, then owned by Sophie Gravel, announced it would release Matsuuchi's game Caravan in two editions, with the gameplay being identical in both versions of the game, but the settings of the game being different, with one set in the Middle East of Earth and the other being set in a fantasy world with crystal golems. Gravel sold Z-Man Games to Asmodee, started Plan B Games, then the company announced that Caravan would now be a trilogy of interconnected, yet standalone games all bearing the main title Century and all set in the real world .
Fans objected, and in the end Plan B Games decided to release Century: Golem Edition anyway. That being the case, Plan B's Mike Young made it clear that this was a one-off publication — "100% fan service for those eager for the golem edition's manga art" — with no plans to publish an entire Golem trilogy. The art was already in hand for this one game, after all, and none of Plan B's publishing partners wanted to release the fantasy edition of the game; they all wanted the version based on real-world history, which means Plan B was on its own for this release.
Still, people kept asking for golemized versions of Century: Eastern Wonders and the just released Century: A New World, and now Plan B Games has decided to continue the fan service with the Gen Con 2019 release of Century: Golem Edition – Eastern Mountains. Here's a summary of this item:
Century Golem: Eastern Mountains reimplements Century: Eastern Wonders but with vivid manga-inspired art. Explore the new gameplay elements and combine this game with Century: Golem Edition to play the unique game "The Call for Adventure".
