These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Informed Wrongness: Played for laughs in later episodes. James was asked where he plays with his Game Boy Colour. Whatever he answered, the announcer always told him he was wrong.
Moment Of Awesome: During one Season 3 competition, the green team held the lead for most of the week, winning the first three shows. When the yellow team finally won an episode, they only retrieved two keys, leaving them about 450 points behind. On the Friday show, the yellow team won the Computer Challenge, meaning they won the episode by five points. Still more than 400 points behind, they needed to find five keys in the Maze to win the week. The entire studio was in hysterics before the Key Run, and in a rare move the entire week's players were shown standing behind the yellow team's desk watching the live footage. The runners found four keys quite quickly, but couldn't find a fifth. With twelve seconds left, the yellow player grabbed a fifth key and the half of the studio audience represented by the yellow team screamed so loudly James' commentary couldn't be heard. The yellow team ended up winning the week by less than 50 points in a ridiculous come-from-behind victory...and the icing on the cake? That last key was the Bonus Key, meaning the contestants won a Game Boy for their trouble.
The "two-key rule" of earlier seasons giving way to the "one-side rule" of Season 4. Some fans thought this made the challenge of running the Maze in the Key Run easier.
The Season 4 Maze revamp got rid of most of the original maze — favourites like the green stairs, Pirates Cove, and Ice Slide were replaced by a castle, a dungeon, a pet shop, a large piece of cheese (complete with puppet bird and rat respectively), and a row of toilets hooked up to smoke machines. The Maze was also significantly larger, and the players on the right side now entered on the far side and exited in the centre at roughly the same location as the other team.
