The quadtree is the two-dimensional case of a broader family of space-partitioning data structures. Octrees extend the same idea to three dimensions (splitting cubes into eight children), KD-trees use alternating axis-aligned splits (splitting along x, then y, then x again), and R-trees group nearby objects into bounding rectangles. Each variant makes different tradeoffs between construction time, query speed, and update cost.

Towerborne was originally envisioned as an always-online MMO-lite action RPG brawler. Players would group together with their friends in a shared social space known as The Belfry. From there, players would venture out to the hexagonal world map and enter into 2.5D side-scrolling brawler combat missions. Loot, quests, and an ever-expanding world map provide a compelling "just one more" gameplay loop. The live-service structure meant the game would be ever-changing and expanding with new content and features continuously releasing over time.
