Game engine architecture is the foundation upon which every feature stands. And like any foundation, if it's weak, everything on top crumbles. A solid, scalable architecture is critical.
Today, ECS (Entity-Component-System) is the dominant model in the industry — but it's not without trade-offs.
So, at first I was doing a funny experiment, making an FNF engine from scratch. But while exploring game architecture, I decided to explore a different take:
A variant of ECS that aims to be:
- 🚀 Faster (reduced redundant queries)
- 🔌 Modular and extensible
- 🧵 Naturally parallelizable
- 🌐 Better suited for real-time and online systems
This led to what I call RECS — a Reactive ECS written in Julia.
Systems subscribe to archetypes (shapes of components) and get dispatched relevant entities per tick.

Would love to get your feedback — and hear how others approach scalable engine design.
