The first is "You misunderstood me. I'm hours into the game; that quest got stuck in the first hour or so, I didn't realize it was stuck, and rolling back to before I acquired it would basically reset all my progress. So it's just stuck there, like a splinter, reminding me how broken the game's mechanics are. Getting to live out twelve-year-old-me's fantasy of fighting Adam Smasher hasn't offset the irritation because that's my flavor of OCD."
But had the situation been as you expected, my response would have been "Because I respect my time more than these developers do and there's a literal sea of other games I could be playing that don't make me replay around script bugs."
As for the respecting time thing... does TurboTax respect my time while showing me a false progress bar when it actually completes its analysis near instantly? Does Microsoft respect my time when Edge constantly pesters me with popups asking to be the default? Does Instagram or Facebook respect my time when they pollute my feed with their business objective bullshit? Does a cop respect my time when he pulls me over and spends 15 minutes running my information? (Like WTF is he even doing... he punches my info into cop google and it spits out an answer! Where is all that time going!) What about if they arrest me? Does the radio respect my time when it airs commercials?
Another answer is: temper your expectations. Take the L and move on. The sunk cost fallacy is real.
I agree. That's why after deciding I wasn't having enough fun-to-bugs ratio in CP2077 about halfway through the game, I gave up and played something else. I've been playing quite a bit of No Man's Sky as of late. It's also buggy, but more fun. Satisfactory is a delightfully tight experience. Kerbal Space Program hides its bugs delightfully behind the overall "Failure is the point" game mechanics. Or I could play basically anything on a Nintendo Switch (main console, not the store) and get a nearly bug-free experience because Nintendo enforces some pretty stringent quality standards.
Everyone's preferences are different. Me, I don't get the buzz from the AAA-ness of a CP2077 to offset the annoyance of the underlying mechanics being kinda boring and kinda buggy.
... I'm not sure what to make of the comparison of playing videogames (an experience I spend double- or triple-digit dollars on for entertainment) to the experience of chores in real life, so I'm setting that aside.
