Wolfire Games is a tiny studio. Wikipedia says 4 employees. Development of Overgrowth is mostly one person, who documented the whole process in fascinating weekly videos: https://m.youtube.com/c/WolfireGames/videos https://m.youtube.com/c/WolfireGames/videos The title says "game engine" because the artwork remains proprietary (similar to old id games, buy the game to get it). However, just to clarify, all the game code (including gameplay logic, which is sometimes not considered part of the "game engine") is Apache 2.0.
