Uhh, this is a strange one. It's definitely not about representing the player. Concerns about representation, which is a multidisciplinary concern hardly exclusive to videogames, nor even especially different when they're the topic, are about the means that media uses to present any demographic. It's about ensuring that a multitude of games invest in good practices so that they (1st) serve the interests of misrepresented demographics (2nd) build a collective awareness of a demographic that is collectively positive, (3rd) fight against negative archetypes , and a hundred other things. This is not especially about players. Developers shouldn't be concerned about representation of women just because women play games. They should be better about representation because good representation is an ethical good that, though benefiting everyone, benefits especially those who need it the most. It's not just transgender players who benefit from transgender representation. They benefit from it most directly, and benefit the most, but in fact the benefits of it start once positive representation nets positive social change and that is a multi demographic effort. It's not even just the people who play games that benefit/suffer from good/poor representation in videogames. Women who will never even play videogames would benefit from good representation of women through the sheer cultural impact that videogames have on the culture.
Also not a joke and frankly quite easy to see why? Representation shouldn't be a choice that players can choose not to see, it should be integral to the experience of play regardless of whether the player wants it or not.
