Well, I think,
If Bismarck had set the example in the Franco-Prussian war by making extensive use of airships, other major powers would have invested in the technology. Then, WW I wouldn't have been a savage meat grinder, but a sophisticated warfare, technology to technology. America probably wouldn't have been involved. Activision probably would have made games like, Call of Duty: Spanish-American war, or Freedom Fighters: Civil War and Civil Rights, promoting important American historical events without so much needless violence.
