I read a few parts of that years ago, but that series never sat very well with me. Because it was so prominently placed on the only major PS website at that time, too many people took the whole thing as game fact rather than fan fiction. It was hard to talk with those people about the games.
The authors made a lot of assumptions that contradict the games also. That's not really their fault though, since at the time there wasn't a lot of information available like there is today. They did the best they could with what they had at the time.
Everything on the Great Collapse profile here comes straight from PSIV, so I think it is a nice addition to the profiles.
