Maybe a casual game-jam once in a while? Or we could organise the creation of some Mix and Jam style tutorial projects aimed at experienced users, replicating some features from popular games. Showing off what Godot can do and how to do it, in bite-sized open-source projects? GDQuest's free character models would be perfect for this. 👀
Just picture that lil' boï entering an oddly large blue pipe and turning into a retro pixel-art version of himself for a platforming demo. Nothing too deep or complicated, just the whole switching from controlling a 3D character to a 2D character in its own viewport, whose texture is pasted onto a wall in the 3D world and then back to the 3D character. That kinda stuff.
