OK next playtest iteration is complete, and overall I'm pretty happy with the results. One sore spot is that the PKs still aren't building any additional bases. So when something like this happens I resort to some extreme measures, in this case specifically copying the build prioritization info from the successful Drones Faction directly into the PKs: Upside is that I should see the PKs now build more cities. Downside is that their going to play more like the Drones, which really I'd like to see a little variation in my AIs here. Then in order to load this Factional change into the scenario I select Scenario>Reload Faction, and just reload the peace Faction: Then I save and exit. Restoring the Defaults Now that I'm pretty happy with the scenario (i.e. its just about there) I'm going to move all the modified files into a new scenario subdirectory I'm going to name, oh I don't know, how about "X"? And next I the copy all the modified txt and pcx files from the "Virgin" subdirectory back into my main "Sid Meier's Alpha Centauri" subdirectory, thus re-establishing the baseline environment. After that I open the game again, load the scenario (which I haven't placed in my "X" subdirectory), and ensure the baseline graphics are back in place: Then I move my scenario into the "X" subdirectory and repeat the process, ensuring the desired graphics are again being elicited, which they are. Next is to playtest again so as to ensure all my last edits have taken effect, and that I've moved all the necessary files into the "X" subdirectory so that the scenario plays correctly.
