Hi Robo Man,
great work! Being Swiss I really missed the opportunity to be the leader of a Swiss civilization (how could Firaxis dare not to include it in first place

).
The choice and design of the UU are just fabulous. And I have nothing to add about the leaders (yeah, there aren't many outstanding Swiss leaders in history... maybe one could add Adolf Ogi, for his international career, but then again he wasn't that popular and among his greatest achievements is that he told the public how to boil eggs...)
But I have two suggestions to make to further improvements the mod:
1. Use of the ancient Swiss flag (see attachment)
2. Addition of Swiss audio files (German commentaries are utterly unacceptable!)
Does anybody know how to do that (once you have proper recordings, of course)? The second problem is of course picking the right phrases. I thought about that for a while and had the following ideas:
"Nume nid gsprängt" (for military units; means "don't hurry")
"äuä" (for anything; typical for Bern and means just nothing at all)
"he nu so de" (same as above)
"eis, zwöi, drü" (for all those who know the film "cool runnings")
So this goes out to the Swiss in this forum: do you have further ideas or comments? If anybody can tell me how to handle the audio files I will try to record them.
