Video games like covering the time of war. That's not much of a surprise. For about a decade it felt like that was the only time period shooters wanted to cover.
But which is more interesting to cover? The Great War or World War 2?
I think the Nazi element has made World War 2 far more popular for video game developers. There's all of the secret projects that result in time-bending stories about alternate realities, as well as the historical and military aspect for strategy games.
The geopolitical environment around The Great War, however, has plenty of material to mine in its own right. You have games like Hearts of Iron that take that approach, and then there's the opportunity to explore more of the technology (as Battlefield 1 is trying to do).
What do you prefer? Which period would you prefer to see video games cover if they had to pick one?
