Hitman’s not an IP they control as it’s just a publishing deal with IO Interactive. IO interactive added more agents in the Sniper side game that are more diverse but I think it’s the one game. Hitman is probably the weirdest examples where it might not be possible because it hinges on 47 being a completely unremarkable on the outside white man made to be the perfect assassin on the inside by a sinister genetics corporation. That might hurt the core game if you can make an agent who “stands out from the crowd” so I could see them not falling over for Create an Assassin mode.
They could pull off some cool gameplay tweaks if pulled off right using different agents that are deliberately designed to have opportunities not available to 47. That you could have Female agents who could use different disguises to get more opportunities, a non-binary agent who could disguise in male and female clothing. But then that might require huge overhauls on the system for example. But you’d have to roll in drawbacks and new challenges because they are not 47 as well. Could be a Hitman 3 thing but they are planning to keep the games updated as a “Platform” so it could roll back into the old content. Like, maybe not create an agent but different Agency assassins who get different strengths and opportunities but have other drawbacks compared to 47. Not as dumb as those awful nuns in Absolution though. Think more John Wick Chapter 2. Having different abilities to go through those big complex sandboxes with would be really cool.
Though speaking of WB. They have been one of the better publishers for diversity. Mortal Kombat has always leaned into the ethnic cast and the last one was great. Arkham Origins did that really cool twist on a c-lister called Diamondback by making them a generic white dude in an armored snake costume into a non-binary contortionist assassin who does not speak and it’s played really excellent. The inclusion rider is pretty much a cherry on top for them though hopefully it also means we see more diverse voices on the creative end as well as in game as thats where gaming is lacking a bit compared to what the inclusion rider is doing for Hollywood.
