Awesome Gamedev

A curated list of good stuff related to the development of games. This list contains only free software for code, sellers who aren't evil for physical resources, and free cultural works for assets.

I have also provided a list of resources which are not free, and the reasons why, in the associated Wall of Shame file.

This is released under a Creative Commons-Attribution-ShareAlike license, version 4.0. You can find its text in the LICENSE.md file.
