I don’t think games need an aspect revolving around gender
I think the game is to be played
You’re not playing as yourself, you’re playing from the eyes of a character. They don’t need to match a gender role for the game to be good
Quick opinion in here; You know how some games don’t have options to use female characters right? In my opinion, it’s fine to leave like that. Since some of these games are based on WWI, WWII, The napoleonic wars, etc. Women did not fight in the front so it makes sense for there to be no females
