Keep Circulating the Tapes: After all of the episodes were deleted from The Escapist, there was a period of several weeks when there wasn't anywhere they could be seen legally. Needless to say, their "Piracy" episode hit a lot closer to home. The resulting moral dilemma was averted after all of their old episodes were added to PATV.
One day, Daniel Floyd decided that he wanted to do a report on video games and storytelling. But rather than do a Powerpoint, he put together a video that cited Zero Punctuation as inspiration, and the very first Extra Credits (though the name came much later) video was born. Some time later, he's one of Yahtzee's coworkers and James occasionally participates in debates with him.
A few other examples: Many of the guest artists are Real Life friends of the others and industry insiders, including LeeLee, but all are fans of the show. While detaching her own webcomic Name Game from The Escapist, LeeLee became a rotation artist for EC, since Theus has been unpredictable.
