I have made eight different Godot multiplayer games in various genres, my biggest being SurfsUp on Steam reaching over 150,000+ lifetime players! I previously open sourced a "multiplayer tutorial" for my game "Cooties" to help teach people how I do multiplayer.
I always planned to record a YouTube video of a high level overview of the Cooties projects with a talk detailing what Multiplayer is and how to set it up for your project. The difficulties it creates, and the reward of playing your game with alongside someone else.
I wrote a script to record, but never found the time to sit down and do so. I'd like the opportunity to present this as a talk at GodotCon instead!
