group offers diversity inclusion consulting, whatever that means
It usually means ensuring a lot of small details. For example if you have a native american character, they'd make sure you do not randomly pick a culture that doesn't fit what the character does or their background, that you don't show some non-native stereotypes, that you don't idolize them like in stories unless your specific story calls for that, etc etc.
You're supposed to work with consulting companies like these when you don't have people who can judge this on your own team, because it's so easy to get so many details wrong. Of course it'd be easier if your team already knows how to do it, sure. But if you can't, then it's the right step to get someone external who can help you not make a joke out of a character. Again, unless they're suppsoed to be a joke.
this only exists because companies can benefit from it by getting there ISG score higher because they can say they put diversity in a game. normally consultants where for a specific topic like for guns or history or a culture but sweet baby only does superficial things and represent themselves as experts when there just in marketing no expert in anything to do with the game.
