CUSTOM GAME ENGINES: A Small Study

WARNING: Article moved to separate repo to allow users contributions: https://github.com/raysan5/custom_game_engines

A couple of weeks ago I played (and finished) A Plague Tale, a game by Asobo Studio. I was really captivated by the game, not only by the beautiful graphics but also by the story and the locations in the game. I decided to investigate a bit about the game tech and I was surprised to see it was developed with a custom engine by a relatively small studio. I know there are some companies using custom engines but it's very difficult to find a detailed market study with that kind of information curated and updated. So this article.

Nowadays lots of companies choose engines like [Unreal](https:

	//Moebius transformations in 3d, by reverse stereographic projection to the 3-sphere,
	//rotation in 4d space, and projection back.

	//Feel free to use, adapt and reshare. I'd appreciate a mention if you post something using this.
	//You can also now find this transformation as a component in Grasshopper/Rhino
	//I first wrote about these transformations here:

	//If you want to transform about a given circle. Points on the circle and its axis stay on those curves.
	//You can skip these 2 lines if you want to always use the origin centred unit circle.
