I think Barret was done very well because he was a badass dude first, and an overall interesting character, and his blackness isn't even in the focus. But yea, in the old days, putting black people in a game meant that they will probably have some kind of stereotipical behaviour attached to them like not speaking correct grammar, or being a rasta, or being a thug. That was lazy, and probably not motivated by sjw dogma. A more recent example of good stereotyping and "racism" is the very popular Guacamelee game, which celebrates the mexican culture. But especially in the last few years, we have seen just a surge of black characters and women being pushed into games. And it does break immersion. If not contextually, or design-related (which I doubt many would pull off), then ultimately, because you just know that they were placed there to cater to the loud sjw-s, and "progressives", and normal people who don't care about lore or logic in the story and just want to look at shiny pixels. Some devs can do it right, and more power to them, and to their art. But most are just pushing this because it's popular. And you can just sniff it out. Like battlefield 5. A black dude is in the front of the main menu, with a female-looking asian and a white guy behind him. Yea, ok, putting minorities that are like 2% of the soldiers in ww2 as a selling point totally isn't motivated by anything /s. But nobody cares about multiplayer games, so it's ok.
