I saw that you cannot use the -w flag with using the .spec files @Grautvornix, so I think just building from the .py files will be ok. Was there a specific reason you did the .spec files? Here is an update version of the build script: build-1.0.1.zip

Cool! But does that script work?  (shouldn't it be e.g. "pyinstaller mercator.spec" instead of "pyinstaller mercator.py" ?) Now that is a challenge! No, I don't have any yet, possibly something like the attached (still ugly with the tongue hanging out) 

build.zip (remove --onefile from build script so it doesn't take as long to run the program)

@Alber 0A.D @AsherI like your proposals! If you have options to recover from an almost total defeat, this addds a nice twist to an otherwise straightforward win/loss result. Part of it seems possible already  I keep seeing single ally's units garrisoning into my CC etc. It is just not a strategy I was using so far. Wonder if we can build that into a mod for testing...

Do you have icons for these, @Grautvornix? And here is the update build script build.zip (I included the files @Grautvornix posted above)
