A rough map rather than a ranking. I couldn't order these honestly
even if you asked nicely.
Languages
Whatever the project needs. C and C++ when something has to be
fast or close to the metal, which is fun until it isn't. Python and
Go for scripts and small services. C# if a project already uses it,
JavaScript or TypeScript when it has to run in a browser.
GDScript for Godot.
Then there's the rest, mostly picked up at an old job: Kotlin,
Swift, Java, PHP, MySQL among others. Enough to read what's there and change
something small, not enough to call myself fluent in any of it.
Games
The part I keep coming back to. Usually something you can play in
a browser tab: a weird experimental game, a board game adapted to digital,
or whatever a jam theme talked me into.
Tools
Editor plugins, addons, and the occasional C++ extension when
scripting alone wasn't fast enough. Mostly things I built because I
needed them, then tidied up enough that other people can use them
(hopefully).
Debugging and accessibility
Something that I like and that is quite important to me: Accessibility.
I try to make my games accessible where I can (I am by no means an expert,
but I think I have an eye for things that could turn into problems).
I also like to debug things, like... really dig into the mud and figure
things out several layers deep.
