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:

Core Coding Standard

Coding practices are a source of a lot of arguments among programmers. Coding standards, to some degree, help us to put certain questions to bed and resolve stylistic debates. No coding standard makes everyone happy. (And even their existence is sure to make some unhappy.) What follows are the standards we put together on the Core team, which have become the general coding standard for all programming teams on new code development. We’ve tried to balance the need for creating a common, recognizable and readable code base with not unduly burdening the programmer with minor code formatting concerns.
