HOT GAMEDEVS DON'T GATEKEEP

Inspired by this post by @midwinterhunt, here's a compilation of all the game dev resources I have come across, most of which I use fairly frequently. Most of these are free, some are paid but fairly cheap. Feel free to add your own resources. ✌️

Important reminder: When using basically any works or programs someone else created in your games, make sure you thoroughly understand the licenses and terms it has been shared with. If you don't know what the terms are, reach out to the resource and ask. Don't be lazy about this; it's not only dishonest but it can come back to bite you.

Engines

Unity - Best suited for mobile and multi-platform.

Unreal - Tailored for shooters and high-fidelity experiences.
