The trailer just screamed "Look we have black people now! Please shower us with praise, Twitter and games media." But whatever. They seem like good enough devs not to let this bit of virtue signaling and woke pandering derail the project.
A lot of projects do get ruined by this stuff though. It really has nothing to do with having a black person/strong women/lgbt person in the game. It's all about what the intentions are with the character. A lot of times these days, it means what should just be a cool sci-fi or fantasy story is going to spend too much of its run time concerned with race, gender and sexuality issues. And it's going to have one-dimensional characters. And a narrative that beats you over the head with shitty identity politics.
Writing good stories is hard and your only priority should be making it as good as possible. Injecting thinly-veiled propaganda and shallow politics into the game doesn't make your job any easier. But people are so insanely consumed by politics these days they genuinely think having this kind of stuff in the game is more important than having complex themes, an original plot or well-rounded characters. And that's where the problem lies. It's a question of priorities.
At the same time, people have to avoid kneejerk reactions and give creators a chance to show they can use these elements without totally ruining things. I was skeptical of Psychonauts 2, for example, and while the "diverse" group of kids in the game is by far the worst thing about it, bringing all the fun and humor to a crashing halt, it still didn't stop the game from being great.
