I am a student C++ developer, and while I like game development, I don't like making games. Instead, I like developing the "tech" behind the games, like game engines, tools etc. The reason for this is because it enables me to code without having to worry about creating art resources, sounds, storylines, etc.
I started working on a game engine, but I am having a hard time starting from scratch. I would much rather be given a template to work off of and modify/add as I go. What are some good open source game engine I can fork?
I would rather fork an engine, as I truly want to make it my own, but I need a base to start from.
Please let me know.
