So am I, probably. I know what I'm getting by now, more of the same pretty-but-mediocre popamoler, minus the expectations.
The base game already has a robust immersive sim base
No, it really doesn't. The similarities are superficial, CBP's gameplay systems are highly isolated and prescriptive.
it just depends on CDPR designing good missions around those features rather than making their typical "cinematic" vignettes.
Here you are partly correct, there is a much better videogame somewhere in Cyberpunk 2077 that CDPR could bring to the fore if they just focused on making a
game instead of a movie with clickable intermissions. It wouldn't be an immersive sim, but it would be something...
But there's another requirement that's part of that and that would be rolling a new low-level protagonist. CBP's progression system is an unmitigated clusterfuck, so to build better levels and encounters, CDPR would have to roll it back to get tighter control over its challenges. And you ain't getting that. It's V, it's gonna be level-scaled mid to high, so just make your peace that you're getting more of the same. If you're cool with that, great, if not, save your cash.
