5 out of 5 rating for ZEITGEIST: The Gears of Revolution - Act One: The Investigation Begins
As of this review my group has just began the fifth adventure, Cauldron Born. Also, I do not have the hard copy, only the PDFs of the individual adventures and the compiled book.
From the story standpoint and as the DM for the game, I appreciate the depth of the details, as well as the open ended nature of the adventures. The players and DM are given a vast amount of leeway on how events unfold and are resolved. The conspiracy takes off well from the outset of the path, transitioning smoothly between adventures. I have to give high praise to the second adventure, The Dying Skyseer, which especially shines with its investigation threads. Truly a remarkable, and highly enjoyable adventure for players and DMs. Adventures three and four are greatly enjoyable as well, with adventure three's subtle inclusion of world history tied into the player's story to adventure four's feel as a spy adventure. My player's and I are looking forward to Cauldron Born finishing up the first act, as well as the remainder of the adventure path.
From the game mechanics standpoint, my players, as well as myself as the DM, enjoy the unique nature of the NPCs. Each are well thought out and balanced. My players have commented that each major combat is different from the last and how the unique nature of the major combatants is a refreshing turn from battling standard Monster Manual bad guys. Furthermore, the quality and production standards for the PDFs are excellent, from the layout to the art.
Highly recommended.
