o.k., thinking of it (and editing my user page), there are at least 2 more things, I remember:
- back these days I wrote a QBasic program (one of many, since I programmed half of my daily work with such tools), only for a graphical sorting of that incredible invention tree ... like: "move Riding 1 row up and 2 columns to the left" or "switch Masonry and Writing" ... and the cool thing was, that I had implemented all requirements and possibilities and they were displayed by lines, that changed when moving an entry ... still a bit proud of it :)
- and I puzzled the "codes" for all units and how to position them on the map, and so (with a little bit of "fairness") I could place a settler with a guardian militia at all the perfect places all over the world ... or (with no fairness) it was no militia, but a tank, and not one but 21 or 50 settlers per city to build, to get all roads and irrigation a.s.o. done within the second round :)
