[Fallout] What is the Pepsi to Nuka-Cola's Coke?
gpt
Nuka Cola has COMPLETELY dominated the international market to such an extreme degree that there never was a "nuka pepsi". Because of their absolute market dominance, only regional brands could ever compete, and even then only in their home town. You can see this in Sunset Sarsparilla and VIM in Maine.

I mean for God's sake,  you can even find nuka cola in old Chinese nuclear submarines, so presumably nuka cola was even sold in CHINA at the time of the Great War.
