Now, I realize this game is not and was never going to be Vampire: Cyberpunk Edition, or Fallout: New 2077. This game is going to be a shooter-RPG hybrid, which will lean more heavily towards the shooter side for combat. CDPR clearly feels this is necessary, either for mass appeal or simply to achieve their vision (either way is justifiable).
It's funny because in my case I got some lovely Fallout: New Vegas vibes from the gameplay demo video, especially in the shooter-RPG hybrid-ness of it, although combat in Cyberpunk 2077 seems deeper and more engaging that in F:NV (even at this very early stage of the game). In a way, I wish games like F:NV or the two latest Deus Ex had come up with some of the ideas CDPR applied in the demo, like pointing at people or things in conversations to contextually interact with them, vehicular gameplay, etc.
Nevertheless, I understand some people's concerns regarding an apparent lack of some of the more interesting mechanics already used in other RPGs, like F:NV's skill checks and traits (skills that are simultaneously productive and counterproductive).
I'm not too worried about the RPG-ness of CP2077, I'm pretty sure that stuff like character customization, interesting NPC and stories, and multiple choices and consequences are truly at its core. I do fear, however, that there might no be skill checks or similarly interesting social mechanics. Pointing at things that might open up opportunities in conversations sounds pretty cool to me but, like Witcher senses, it can grow old quickly if they overrely on it.
I'd love that, for instance, you could gain more trust from netrunners if you've developed your netrunning skills through the game.
But it's not a huge fear for me.

A bigger fear of mine is that they end up downgrading some of its mechanics. Things like vehicular combat and interactive world elements (like the ads and whatever else they might've applied that kind of interaction) could end up being reduced or even removed from the final game and that would suck for me.
Regardless, I'm not passing any definite judgement on the game until I have it on my hands.

The biggest of them all is that they either delay it "indefinitely" (development hell) or that they outright cancel it. I really, really, really, really hope that it gets released. I'd rather have it delayed a couple of years that see it go down the Scalebound or Prey 2 road.
