Godot, hands down. I used it with my then 12 year old to recreate a game that she used to play with her friends. I was pretty smooth sailing and the result was better than we expected, so we plan to release it in the winter.
We don't expect a lot of downloads or to make any money from it and that is not the point. The goal was to produce a minimal game completely DIY and from scratch. For the first version we created everything ourselves, including the assets. For the version we plan to release we will have a couple of select bought assets, but it was a good path to start with our own creations.
A not to be underestimated bonus is that GDScript is similar enough to Python that in my opinion learning it is useful beyond Godot and game development.
