9 years, 10 years, an eternity... pretty much the same imo mate
i do actually believe that this should be possible in 2021, a game that has great storyline and decent open world, especially something that almost took a decade to make. a game will always have flaws, there won't be a 100% perfect game ever, but when people start making thousands of threads about the same thing and many are willing to pay for just a bit more extra content (and a finished game, is that too much asked for?), i think it is legit to say that something is missing.
i also believe that many devs would have postponed the game 2 more years to finish it, but the pressure from higher-ups forced them to rush in the end.
Personally, I ask for as little as a finished game and activities with story characters or something after a storyline ended, otherwise an open world game is useless imo, could aswell be COD story style then, finish and forget, unless it's GTA where you just play for shits n giggles after the main story. i just can bring up TW3 again here, after the incredible story, the game felt empty, from 100 to 0 real quick.
CDPR has the ability to make games that bind the player emotionally to their characters, if you finish the story and suddenly the character with whom you spent 100 intense hours disappear into a lifeless normal npc, it kind of breaks you emotionally.
EDIT: To your edited comment, I don't underestimate the ressources a game this big needs, but I don't understand why they are not ambitious to make a game that took that long and that much manpower as good as they possibly can - because obviously, they haven't reached their potential at all.
