I have a few text based games which I write in JS so they can be played on the web. I use an off-the-shelf story format (Ink, though Twine is a popular competitor) and otherwise write the engine myself.

I've started using Unity for some 2d games (and faux isometric ones) and it's a bit of a blackbox but not as much of one as I thought it would be. Still not a fan of their licensing on the asset store though you can publish packages to git and itch.io without EULA nonsense.
