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.
