A quick google brought up a steam discussion in which some people are saying that after a patch for Rome 2, 50% of all faction leaders in a new game became female. Some people liked that as they claim it is alternate history, some said it's ahistorical and breaks immersion. Now, I don't own the game to verify this, but nobody in the discussion was claiming it wasn't true that the patch did this, they were only debating whether they liked the change or not.
I think a big part of it is that this was delivered via a patch rather than in the base game, and people were telling those who didn't like the changes either to not have the patch at all (unacceptable) or just "mod it back the way it was". "you can just mod it away if you don't like it" isn't a very good justification for forcing a change into everyone's game, since that works both ways. People who wanted the change could have used a mod to get it, by the same logic. Or, it could have been included as free DLC. A choice to support more progressivism and options in the game would have gone down a lot better, and by making an active choice to include the DLC people are making a statement. Trying to shoehorn ahistorical gender fairness into everyone's games, including those who play historical wargames because they like historical accuracy is in fact heavy-handed and patronizing.
It's a fine line obviously. The argument against it isn't that women cannot be leaders, it's that a game set in a historical time period should adhere to the norms of that time period even if they don't gel with modern norms. I for one would be upset if the latest Hearts of Iron game decided it was going to implement a 50/50 gender ratio for all generals and politicians, because Hearts of Iron is all about historical accuracy. Sure, highlight female political, military and scientific figures that actually existed and give the player the choice to promote them, even if they weren't promoted in real life. But turning the models of actual historical nations into feminist nations is just silly and unhistorical and immersion-breaking.
