There are multiple anime voice actors who are in unions, for example Troy Baker, the English voice of Naruto's Madara Uchiha as an example, but I think something even bigger is that getting a traditional actor to come and voice act is very, very expensive to begin with, and one of the biggest examples that comes to mind is Keanu Reeves for Cyberpunk 2077.
One of the biggest reasons that the launch of Cyberpunk 2077 went the way it did was found out to be because simply getting Keanu Reeves to be in the game, paying him and his portions of the game were a large portion of the budget, which ended up making the game run absolutely terrible on PS4 and XB1, but in general, even hiring the voice actors that are on cartoons is pretty expensive, as although someone like Tara Strong has been in dozens upon dozens of American kids' cartoons, there is no anime or Eastern animation in her filmography at all.
Speaking of voice actors however, there's three voice actors who are members of Hololive's English branch. Ouro Kronii, who is Dottovu; Nerissa Ravencroft, who is Caitlyn Myers; and lastly, Elizabeth Rose Bloodflame, who is Eileen Montgomery/EileMonty.
But aside from that, it just makes sense that anime can't get the top tier actors or even some of the most prolific VAs for American cartoons, because anime for many of those top tier actors is seen as weird, as well as not paying enough for many of them to see it as worth it. I'm just not sure the clique situation with current English voice acting for anime will be able to change without the studios either deciding to hire dual language VAs in Japan or actually putting good money in for better voice actors, as I do understand why many people say that English voice actors suck as a whole, even if I disagree.
All of these points about how much games are fucking themselves over in this regard are valid but I would point to something even more basic and it's that many of these developers seem to refuse to playtest their own projects towards the release date. They need to play their own games, period, if they did they would have caught many problems before they became such massive PR disaster.
If it were me I would make it so that everyone from the CEO to the janitor and security guard have to have mandatory play sessions so that everyone knows what's going on with the product they're involved with. I'm playtesting my own game right now and shocker, despite me being fairly confident in my code, I'm still finding bugs occasionally and behaviour that needs fixing. If CD Projekt Red had bothered playtesting their own game for five seconds on machines other than their high end gear they would have been horrified.
You are giving them way more benefit of the doubt than they deserve. The truth is that they are very well aware of potential issues but are either too stubborn or are too arrogant to make changes.
You'd be surprised, from the insider leaks and second hand accounts we're getting from ex-employees apparently these massive companies don't even see their finished product in a lot of cases which they should be completely embarrassed by if that's true. Now my empathy completely vanishes of course if it turns out that's not what is going on and for some reason it's gotten worse since these guys left.
I suspect games companies currently are far more retarded than any of us initially might think. The ex-Fallout 1/2 dev doing his videos is a great one to take a look at because apparently they would try and sit on a few lines of code for a couple of weeks when in reality it would take him five seconds to write up and implement.
Cyberpunk locked themselves in a Catch-22 with the PS4 and Xbox One. They promised more than really could be delivered on the performance of those platforms. So they are left with severe graphical downgrades or poor performance, both of which would get them panned. They really should have released it as a next gen and PC exclusive and put their effort as such, but with all those preorders, that also gets them.
I get your point about spending money on pricey voice actors, but unless they were going to otherwise spend that money on good writers, it was still going to suck. It's not that poorly put together on hardware that can handle it, it's just boring.
