Fridge / Dungeons & Dragons (1983)

• The players have classes that don't match their personalities, don't use their powers effectively, have trouble picking up on the dungeon master's instructions, and keep arguing all the time. That's exactly like a real game.
• "The Girl Who Dreamed Tomorrow": As the episode's title states, Terri's visions are specifically of "tomorrow." So how does she dream of herself meeting up with Bobby in the real world when Bobby and the others have remained in the Realm for weeks or months? Because "City at the Edge of Midnight" confirms that Year Inside, Hour Outside is in effect — back on Earth, it's still the same night the kids got on the rollercoaster that sent them to the Realm, and no matter how many months pass from their POV before they get back, they'll still get back on the same night they left. Terri gets back to Earth (where it's still that same night) on the day (in the Realm) after she had that dream... so, from her POV back on Earth, when the kids get back that same night, and Bobby tracks her down the next day, it will be "tomorrow."
• Diana reveals in "Child of the Stargazer" that her father is an astronomer. That probably explains how she ended up named after the Roman goddess of the moon.
• The show creators admit that The Complainer Is Always Wrong was an Enforced Trope placed on them from higher up. But like any writers worth their salt? They put all the complaining on Eric the Cavalier, who (as others have pointed out) is derided for his opinions, but actually turns out to be spot-on about most of the things he's pointing out.
• Dungeon Master claimed to be their guide, he never claimed to be their friend. As any tabletop gamer knows, the dungeonmaster is supposed to put the player's characters in dangerous situations and refrain from helping them when they get overwhelmed.
• Sheila falling into the Team Mom role makes sense when you look at the way her and Bobby interact. She's at least eight years older than he is, and some of the statements they make indicate that Sheila has been doing a lot to raise her little brother, probably due to parents who are working and/or divorced. This also explains why Bobby is the most at ease with being in The Realm, his "mom" figure is already there with him.
• Diana's fear of getting old? Considering that, even though she's in her mid to late teens, gymnasts are considered long in the tooth by 20, this makes far too much sense.
• Of course the series has No Ending, but there's a script showing all kinds of awesome stuff that was supposed to happen. Every real Dungeon Master has that situation where the players drift off or have schedule conflicts, so the DM ends up with this big climactic showdown designed and ready to go but never getting used.
