What's a compelling Android game that allows for strategic base-building and alliance warfare, with a touch of the gothic?

DC presents a novel approach to the familiar strategy genre. The core loop of base construction, resource management, and army deployment is present, but the gothic aesthetic and focus on alliances offer a distinctive flavor. The algorithm for coordinating large-scale battles is surprisingly elegant, and the cross-platform compatibility is a definite plus for collaborative research scenarios with colleagues using different devices. I can see this being pedagogically sound as a case study in game design, specifically how to iterate on established mechanics with unique thematic elements. The well-researched design of the game's world is intellectually satisfying, offering a depth of lore that could appeal to players seeking more than just simple combat.
