What's an Entity System?
Entity System (ES) is a technique for building computer games, with advantages in terms of: performance, extensibility, game-design.
There are different definitions, and this wiki aims to cover them all - but with a focus on the most practical/popular designs.
*ES approaches - index linking to all the different ES architectures / approaches
*rdbms with code in systems - the simplest possible version of an ES, from one of the most popular approaches
Example games
NB: this is for *games*, not *frameworks* - frameworks are listed + linked all together on the ES approaches page
