The _launch_ was a disaster, as far as a AAA game goes, I will 100% agree with that. However... if you had a decent PC and didn't have unlucky bugs, it was an amazing experience. You could go down any random street and it really felt like there was an adventure behind every corner... and not just any adventure, these things were incredibly detailed.
I honestly just can't agree with that. Those do exist but I wouldn't consider them to be "most." Perhaps if you've done all the side-quests/gigs those will be all your run into? I haven't had a single side-quest/gig that doesn't at least have some associated exclusive lore or dialogue. They've all been on par with the quality of the main storyline missions, imo. I actually prefer them, as I think it really lets you explore more of the world vs just the main character.
In any case, sometimes certain games just don't click for people. I've never liked battle royales for example, despite seemingly everyone being obsessed with them there for awhile, lol.
