Big Boo's Haunt: Creepyville as well as the Haunted Museum in the Video Zone.
Celebrity Edition: On three occasions in Season 2, cast members from then-running Nickelodeon sitcoms would compete against each other. One episode had cast members from Salute Your Shorts competing against each other, another episode had cast members from Welcome Freshmen, and a third celebrity episode featured cast members from Clarissa Explains It All.
Chroma Key: The Video Zone was made possible as part of a soundstage separate from the main set with ladders, platforms, and steps all painted in one color to overlay the platform elements of the game screen.
Early Installment Weirdness: Early tapings had the Pop Quiz consist of a choice between several categories. This was later changes to just going straight to a question related to the board Mikey was currently in, and the choice between categories was now exclusively for the Goal.
Epic Fail: A contestant playing Super R-Type on the Grand Finale managed to score less than 1,000 points...and got a Game Over before time ran out.
It Is Pronounced Tro-PAY: Whenever Sonic the Hedgehog or Sonic the Hedgehog 2 were used, Moore would always call Dr. Robotnik "Dr. Robotonik", always adding an extra "o" to his name for some reason. He would also occasionally forgets a "t," calling him "Dr. Robo Nick."
Nintendo Hard: The Video Zone. So many Game Overs, so many crushed dreams of children wanting to go to space camp.
Obvious Beta: One of the games, played twice during the run, was a very early version of Sonic the Hedgehog 2 which used Sonic 1's Star Light Zone theme for Emerald Hill. The ROM was eventually dumped onto the Internet on November 7, 2006 and was even dubbed the "Nick Arcade prototype." Not so obvious during the show's original run, its appearances caught the attention of the Sonic fanbase during the repeats on Nick GAS.
The unaired pilot also had footage from a beta version of Sonic 1, while the actual show used the final American version of the game.
Pilot: "Hey you guys, pause those VC Rs and put down those joysticks; it's time for Nick Arcade, the show that tests your video savvy and video game skills. Today, one lucky team will actually get to go inside a video game, for a chance to win this fabulous bonus prize, a trip to Universal Studios Florida. And now, here's the host of Nick Arcade, the best-dressed Tetris player in the free world, Niels Schuurmans!"
Season 1: "Behind this door is the Video Zone, a place between our world and the video dimension. Waiting to challenge you for control of the Video Zone is one of the Game Wizards. Is it... Merlock, Scorcha, or Mongo?" *Camera pan over contestants* "These two teams will compete for the right to enter the Video Zone and face the Game Wizard's challenge. Who will it be? Find out today on... Nick Arcade! And now, here's your host, (insert preparatory phrase), Phil Moore!"
Season 2: "Get ready for the ultimate Video Challenge, as these two teams go head-to-head with a maze of electronic obstacles for the right to face one of our Game Wizards in the Video Zone! (insert preparatory phrase here, like "Strap yourselves in!") Here comes...Nick Arcade! And now, here's your host, (insert preparatory phrase), Phil Moore!"
Undesirable Prize: The grand prize was often a trip to Universal Studios in Orlando...where the show was taped. Basically, this meant that if you weren't impressed with the park the first time, you "won" the opportunity to see the same things all over again. On the other hand, if you enjoyed the park, you got a return trip on Nick's dime.
