Peter had an interview way back during campaign days that covered LGBT inclusion. Here's a piece of it:
"I don’t think it’ll be a major element, mostly character detail and context. It’s important that we strike the right balance in making it feel natural, but also not call so much attention to it that they’re defined by their sexuality or gender identity. First and foremost, we want to make characters that are defined by what they do and say, not by what they happen to be. So, for example, a side-quest line might be about an Incarnation that Ajna has absorbed that’s worried about their lover. As you do the quests, and you find out the lover is the same gender. Not really meant to be a big reveal, but it’s there, and if you think back on the character and other situations in the game, you’ll realize it makes sense."
The rest of the interview is
here. With 25 incarnations there's a huge amount of room to have diversity, which is something that's been a goal of this whole project (having it set in a South East Asian setting with a western world being foreign- something typically presented as the other way around, among other things), and from different characters we've already seen differences being celebrated in ways that don't limit them to stereotypes or by these factors. I think the team will definitely be able to do a good job of making all of this feel natural in the story, and inclusion really means a lot for a wide audience and myself so I'm super glad to see it.
Anyways, we were able to see Indivisible at E3 more than ever, and I'm glad we're getting a lot to talk about lately! Anime Expo is right around the corner and we always get a great amount of content from them so I can't wait. Hope to see some more character implementation, Phoebe and Ren are already somewhat implemented afaik so seeing more of them and others would be cool.
