Does Freeciv use this approach? Or any other significant open source game or roguelike?
ECS sounds somewhat like how I was thinking of a civ-like game engine while falling asleep a couple months ago when I was thinking why Civ scaled so poorly under some circumstances: traditional games used to have everything in memory, but civ type stuff could just have a database with some indexes and spatial indexes for quick lookups, but otherwise just sweep the various tables. Thus the size of your game was more constrained by disk space than RAM.
Per your discussions with cache conservation/thrash avoidance, does ECS work well for mapping entities to specific processors so that cache-hopping doesn't occur in modern multicore processors and NUMA stuff?
