If you’ve already got experience with general programming, that helps a lot, you can probably just go straight into a super simple game. My go-to recommendation for programming in general is “make simple something that already exists”. That gives you goals that are very clear, and reasonably achievable, so you can start getting some of that satisfaction feedback quickly. For a game, I’d say do something like Tic-Tac-Toe, Battleship, Solitaire… something that isn’t gonna require a whole lot of art, just to get going, and isn’t gonna take weeks to get a working prototype.
Godot definitely sounds like a good bet to get going. Even if you end up moving to another engine for projects in the future, that doesn’t invalidate your time spent on this one.
Horseshit. No way is Elon’s popularity that high, after he so effectively alienated himself from both US parties. I’m guessing the poll just asked about supporting A third party, not Elon’s third party.
