Probably. But I think the intention is to attract customers, not to push some kind of agenda. So instead of toning it down, I think it would be better to make it explicit and make games from different perspectives.
For example, make a WW2 game from the Soviet. Or perhaps Japan in the Russo-Japanese war of the early 1900s. Those could be as biased as they want because they’re telling the story from a certain perspective.
