A.M.A.N. Trove was aimed at smaller parties and solo players who struggled to participate in the large-scale multiplayer content that made up the majority of endgame in 2018. To suit our target audience, we took the existing "treasure chest battlefields" and rearranged them while limiting the number of new features.
Our concept was to create content that was straightforward, easy to get into, enjoyable in a short span of time, and emphasized playability. Those ideas were then embellished with elements that hardcore players could also enjoy, such as a chance to encounter powerful-but-rewarding enemies, rewards that embraced the content's theme of risk-and-reward, and related objectives in Records of Eminence.
Looking through our design proposals from back then, I see key concepts like "Strike it rich in Vana'diel!" and "A sense of thrill and excitement!" and I certainly hope those feelings were successfully conveyed to our adventurers. (Yasushi Yamazaki, Planner)
