He basically says, "in every game there's what you ideally want to create, but then scheduling/money/system memory causes bits and pieces to go. Your ideal (in your head) isn't a sellable product. After the release I felt pained at my inability to deliver a finished product."
"There's nothing more or less than what was publicly released. It was my decision to leave SE. Even though I was sick, the truth of the matter is that I let down the staff, the company and the fans expectations"
wow, that's harsh. :\
