I honestly can't understand those people who complained about long story. Like, since when it's became a bad thing? On the contrary, Its absolutely awesome when you are able to play a game for 100+ hours, exploring and having fun. Especially if the game keeps you attached to the story during these hours and not gets boring. I think this was the problem with CP and not complaints, they just didnt know how to make a long game without it getting boring.
The waters are already cloudy - but they get murkier when you factor in the three game length aspects. 1) Main Story, 2) Total Complete Play-through 3) The time to completion that is satisfying for a player. (This last one may mean 30 - 50% completion of things plus the main story for example).
So I am one of those people who don't want super long games (3rd point above), and I'll try to explain to you why.
I don't have the time or energy to invest in a game that is going to take me hundreds of hours to hit that third point (feel that I've completed it enough to be satisfied). If a game takes hundreds of hours to do that, historically it will likely end up taking me months or even years to finish (if at all), and even then begrudgingly. I want to be able to drop into a game and play it to a point I feel I've enjoyed myself and do other stuff over a period of time where it doesn't end up feeling it's a chore.
The OP wasn't specifically talking about the main story, so I won't either, Cyberpunk hits that third point right on the head of the nail for me. Thus I've completed it a few times since release. Each run I feel that I've achieved a play-through I'm satisfied with.
I still haven't finished Dragon Inquisition, I've only done one complete play-through of The Witcher 3. I've played ~30 times through the first Mass Effect, countless through Dragon Age Origins, and even a few through Mass Effect Andromeda. (The sweet spot for me is hitting that magic 3rd point between 30 - 80 hours approx)
I'm not saying I'm right, and you're wrong - I'm just trying to explain that for people like me, going longer overall can be a negative against the game.
Now, if you want to get into specifics about the main game or the 100% completion time - they're different things that deserve their own threads.
