First, the game itself: good on several counts, shaky on others. There are four main playable characters, all guys: Noctis the prince, Gladiolus the bodyguard, Prompto the cheerleader, and Ignis the strategist. They bro the hell out of everything they do, taking pictures, cooking meals together, confiding in one another and generally bantering through the adventure. I find it extremely amusing, and their interactions feel pretty healthy for the most part, if relentlessly performative.
Female characters work their way into the story at points. There's Lunafreya, the princess who Noctis is travelling to marry
I certainly roll my eyes at these scenes. Maybe I should be harder on FFXV for this, but all I can think is, well, how typical. How ordinary. How normal for an RPG to feature a character whose role is primarily visual fanservice, and how typical that she's a woman. In a way, what concerns me isn't an exceptional depiction of a character, or even a particularly terrible one, but the ordinariness, that sexist motifs are common enough that they have names: "Fanservice" itself, for instance.
The bros too invite this comparison to typicality. On the one hand, it's less common for RPGs to focus solely on a main cast of men, and so FFXV registers as an important and novel variation on the genre. At the same time, I can only think of one RPG that has focused solely on a main cast of women, and that's Magic School Lunar, a Japan-only RPG. Across the genre, there's room for individual games like FFXV; at the same time there remains so much to be done regarding featuring women in main and supporting roles. I think it's important to maintain both viewpoints at once - the individual and the systemic - because it's possible for an individual game to do something very well, and for that very same thing to be exclusionary if it were done by most games across a genre.
I feel like the distinction I'm drawing comes up again and again in the things I enjoy: I like Star Wars but reject the predominantly male-focused elements of the original trilogy which are typical in sci-fi (fanservice, having one prominent woman in a supporting role).
