There is more than just history by country, what about the history of music or theater or art or computer science or math or religion or the video game industry? Everything has history and its always exciting in some way to see where you and the things around you have come from. Its epic drama, but its real epic drama.
Also there is different degrees of each. You could talk about the different generations of the Video Game Industry, or you could go into 3rd party companies and talk about how they developed and who came at what time and how. You could talk about game design decisions and how they influenced the path of a company in relation to customer reception and even how success of those designs and character models related to its marketing, world events, or cultural changes.
Seriously there is so much information in history that is interesting its crazy.
Having said that, World history delves into the history behind many of the things mentioned above. In that, I personally find it a bit more interesting.
