Big, well known actors in video games have been a thing for a long time now? I remember games from the 90's that had actors like James Earl Jones, Tim Curry, Bill Paxton, Randy Quaid, and so many more growing up.
What's interesting is, it doesn't seem like it's expanded or shrunk. Most games don't hire big actors, but a handful of huge budget, AAA things do. There's also big range in how good these actors are in the game... JK Simmons, for example, was awesome as Cave Johnson in Portal; but his performance in Baldur's Gate 3 is, by far, the worst in the entire game IMO.
It makes sense for those who are big enough in the Game Industry (which is now several times the size of the Movie Industry in terms of revenue) to try and do the same as movies and leverage that sweet brand recognition of celebrity actors to sell more copies of the game.
However I suspect it doesn't work quite the same in practice as the "main character in the story" in games is almost invariably the player him/herself and those famous names will never be more than secondary characters with limited interaction possibilities.
They could do the cyberpunk or fallout 4 thing. Have Keanu Reeves in your head, or get someone known to voice the protagonist (only unlike fo4 in that the PC VAs are otherwise unknown afaik).
