Here's a quote from April 2001, supposedly from a disgruntled Retro employee who was unhappy about working 60 hour weeks:
"Metroid looks alright, but it ain't nuthin to write home about, so we'll see. As far as the art talent that is here, it's not as great as others would lead you to believe. It's mediocre at its best."
And that game went on win like a million awards.
Further down on the page, there's a scan of letter that Nintendo sent to retailers in early 2001 asking them to take down advertisements for XBox. The story also mentioned that Sony took a different approach - hiring saboteurs to rip up XBox displays.
