For example physics managing many moving objects or thousands of units casting area-of-effect spells against each other would ideally require something more refined, like an octree or other spatial partitioning to speed up entity-entity detection and If your levels are cluttered asteroid fields, you'll need some sort of graph (octree, perhaps) and then A* or flow fields could be used for pathfinding.
