Yeah, I do hope CDPR pulls off something similar. For many reasons I doubt it (even though they managed to turn a buggy Witcher 3 into one of my favorite games ever), but I do hope so.
I'd easily pay 30-40 bucks for this game if they fixed the performance issues and bugs, made the open world even slightly better, fixed the non-existent AI, and tweaked a bunch of the gameplay.
If they also managed to make driving fun and the choices more meaningful, I could imagine paying full price even. From what I've heard the story is okay, but that it has too much 'illusion of choice'.
