I've built the Texel ASCII Art Editor (https://crates.io/crates/texel) using Specs (https://crates.io/crates/specs) as my first experience with ECS.

The original goal was an ASCII game but since I needed to create the resources for it it morphed into Texel. I think the use of ECS here wasn't a bad decision but Specs proved to be just too cumbersome and overoptimizing.

As others have mentioned ECS is a bit "loosly defined" and each implementation seems to go over the line to add more specializing one way or the other. I want to switch to something more simple and elegant like DCES (https://crates.io/crates/dces) for my next refactor.

I think for "runtime resource management" ECS is fine if you need a fairly large, distinct pool of entities to handle. One of my main usage problems was the re-use of same components in the same entity.

E.g. imagine having an entity with a global world position, but also an internal position for something like "last cursor position". It's not possible to just "add another Position component" to the same entity, for good internal reasons, but still. It's pretty important people take these kind of limitations into account before planning out their entity/component maps.
