I don't identify as a gamer. I occasionally participate in board games or an amateur football match, and I rarely spend time playing computer games. But I used to.

One remnant of that time is civilization, or its open-source spin-off, freeciv, that you can also play online for free. I already tried and failed to use the freeciv game engine to illustrate the concept of Astro's Islands Architecture.

I then used AI for my React recap post last year, to generate a pseudo drawing inspired by my civilization idea and the visual style of my hand-written sketches.

Here is another illustration that looks much more like the actual game.

What made me want to write another article is yet another aspect of that game: the technology tree.
