At Devcom last month, senior narrative designer Arden Osthof gave a talk entitled "Playing with gender: A design framework for character customisation," giving tips on how game makers can improve their protagonist creation tools to be more inclusive.
Osthof previously worked at Ubisoft, with past projects including the Anno series and Tom Clancy's The Division 2, and is currently a freelance narrative designer working on Rho Labyrinths' Mars Vice and Screen Juice's Morbid Metal.
They have been researching character creators since 2017 and specifically how gender-inclusive these tools can be, and what sort of options they can offer for players to express and project themselves accurately.
