CUSTOM GAME ENGINES: A Small Study

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 or Unity for their games (or that's what lot of people think) because d

// An outline shader made for Unity with the help of @OverlandGame by @miichidk
// It adjusts the size of the outline to automatically accomodate screen width and camera distance.
// See how it looks here: https://twitter.com/OverlandGame/status/791035637583388672
// How to use: Create a material which uses this shader, and apply this material to any meshrenderer as second material.
