Eh, they all have varying levels of no-idea-what-they're-talking-about style anecdotes. Quill for example seems to have no clue that the value of a campus is not solely restricted to it's adjacency bonuses. I mean libraries are available as soon as a campus is. He could have had a campus with a library for a total of 3 science output very early in that game yet he waits till turn 80 to get a campus in his capital and he doesn't even place it optimally.
He addresses this and shrugs it off to opportunity costs but there's no way around the fact that he lost over 100 science on that decision.
Keep in mind I'm not criticizing his play. Second time behind the wheel I don't expect mastercraft play. But at least don't pretend like you made an optimal decision.
Also, a very common theme between all of these playthroughs is that nobody seems to fully improve the tiles around their cities, even missing out on resource tiles too.
