Hello everyone! I think one neat thing about ECS is that we can have something that requires far less work than an actual sample/demo and still gives us useful insights about patterns and good usage of ECS : we can just share our list of Components, Systems and Archetypes (or other often used Entity "signatures") in our games, projects, or part of it (restricted to a "World" for exemple). Or aven a very simplified version of it. I believe that just with this list, you can learn a lot about the logic and design of a given ECS-driven game system. For exemple, how one managed his input/control, his event-driven mechanics, his specific Physics Simulation (boids was a neat exemple, maybe fire spreading? or fluids?), his crafting, his inventory, his procedural terrain or even higher level, his small STR, his turn-based tactics game, his AI etc... It is difficult to find good ressources on robust patterns for specific mechanics, or type of mechanics in ECS, so I think it could be something nice! Also I believe it would be quite cost-effective in term of effort required vs insight offered... The bonus would be to explain how you approached the problem, and reframed your mechanics in term of Data and Systems that operates on it. I do not know, maybe I am wrong, but I believe this would be useful to many!
