Prefer male generally but some female protagonist games can be fun even if they all tend to lean towards the same thing. Good old corruption, cheating, and all of that nonsense. It's fine in doses I guess but it can definitely get old.
I can agree with that, it can be incredibly jarring to have a sudden warning in game. I would assume that the tags would be enough to let people know what's in the game buuuuut people can be dumb
