It's really not like GTA. I mean, superficially it might resemble one. But in GTA you drive around doing whacky things that are meaningless and don't affect anything until you engage in an B-movie script that has interactive elements. In other words, nothing you do really matters, it's all a one linear story and anything else is a failure state.

Cyberpunk has also some of the random mayhem you can do, but every time you engage with the plot, there is dialogue choices and they matter a lot. There is no one single ending, and the mood is a lot more somber and thoughtful than GTA or RDR ever managed to even dream of.

The actual gameplay is basically a liteFPS with RPG elements, interspersed with minor stealth, problem solving, puzzles, and other mini games. Depending on play style, or level of completionism, the FPS+ is anything from 40 to 80 percent of the gaming time, the rest beign spent agonizing dialogue choices and other plot twists.
