Vice City (the game) also had minorities - Latinos, Jews and so on. This can be said about every GTA (El Burro - Latino, LGBT and animal lover :D) The difference is not their mere presence, but the overall tone and inspiration. This Vice City is not a gangster Miami, but a degenerate Orlando.
I wouldn't judge it so harshly. Finally a game that seems to deal with some issues in real life. Think what you want about big-assed negressess rushing on top of cars - this is the world we live in. GTA only changes the proportions, but not the ingredients themselves.
In other words, like the world, like GTA.
But there's a difference, isn't there? Crime stories are popular because they allow us to overstep the boundaries of our mediocre reality. The world of crime is a world of possibilities. Living fast, danger, beautiful easy women, (real)power--that is, power of life and death. The crime story is, in a sense, our form of epic, and the only way to depict certain larger characters outside of fantasy and science-fiction.
The grime and "degeneracy" are a background for this kind of setting, because it's there you can escape. The corrupt cop, the street hooker, they represent a kind of freedom, as well. Through them you get to know a different kind of world, an underground world without rules. It's the hidden promise of that world that pulls you in.
I put "degeneracy" in quotes, not because these things aren't degenerate, but because I believe there are worse things we don't talk about. A cop who takes bribes is less degenerate than one who spouts politically correct bullshit for career advancement, for example. Whoremongering is less degenerate than jacking off to porn. The consequences of these things are far worse and you see them everywhere.
The problem with "fat negresses twerking on cars is part of our reality", is that that kind of thing does not let your mind escape, rather the opposite. It imposes our commonplace reality on you at a deeper level, telling you there's nothing else, no outside world to escape to. Mind you, not all forms of crime are equivalent. That's why you have a lot of movies, some great ones, about the shenanigans of Italian Americans, but very little about the constant low level warfare of black America. San Andreas made an effort to depict the mythologized epic story of early 90s LA with its gang feuds and the rise of gansta rap--which, at least in the beginning, had its own originality and glamour--but even then it resorted to a lot of projection and out of place moralizing. The truth is too offensive to hear. Black crime is not glamorous, in the strictest sense it shouldn't even be considered crime, but an animal control issue.
Like someone said before, the worst thing about the trailer is the couple narrative (the woman on top, asking the man to trust her--obvious role reversal). Can't be a guy having fun by yourself, need to bring the girlfriend along. Crime is a thing for men, and not least for the reason that allows men(particularly in some matriarchal cultures) to escape the control of mothers and wives. Crime is sexist by default. That's the only reason it's even interesting, because it's free of the normalizing/moralizing grasp of women. Every good crime story is a "guys being guys" one. And yes, I've seen Bonnie and Clyde. That's a love story with a criminal background. And no, this doesn't look like that either.
Anyway, I've already written too much about this turd. I'll leave it at that.
