Tools
Tools that I use/support that are open source
Krita
My art program of choice, essentially the Blender of the art world.
Godot
A quality, stable game engine with no fees or royalties to deal with. It is still in its early phases but is always improving
best for 2d games, but is making huge strides in its 3d capabilities.
Blender
A trailblazer for open source software that has become the swiss army knife of the 3d world.
Libre Office
Cool alternative to Google Docs and Word. Could do with some better UI design but does the job well.
