Commander Keen/YMMV
- Angst? What Angst?: Molly adjusts to the weirdness of being on another planet (and the weirdness of being rescued by her 8-year-old charge) amazingly well.
- Then again, Mortimer is her little brother. Maybe she's used to this sort of thing.
- Canon Discontinuity: Tom Hall's stance on the 2001 Game Boy Color game.
- Crowning Music of Awesome: Sing it with me: "You've got-to-eat-your veg-ta-bleeeessss...."
- Demonic Spiders: Robo Red in The Armageddon Machine.
- Ensemble Darkhorse: Just ask any non-fan to name a Commander Keen enemy. They'll probably answer "Dopefish". And in fact, there's an official site for people to list cameos the Dopefish has made in other games and show off fanart and other projects featuring the Dopefish.
- Even Better Sequel: Secret of the Oracle and its successors The Armageddon Machine and Aliens Ate My Babysitter are considered the best and most iconic of the Commander Keen games, with its more expansive level designs and superior graphics.
- Goddamn Bats: The Vorticon children in the second and third game. They race around the level at breakneck speeds and jump around in erratic patterns. They can't kill you, but touching one stuns you for several seconds and they rarely appear alone.
- Too Good to Last: Although these games are a fairly enjoyable way to spend an afternoon if you're not busy, they were discontinued before a satisfactory conclusion could be reached, and a number of copyright hand-changes have made an official conclusion more or less defunct.
- Unwinnable by Insanity: Turning clipping off and walking through walls is in some circumstances a non-standard way of beating a level; bad luck if you're required to beat the level by collecting a particular item or person.
- Visual Effects of Awesome: Many people were blown away by the smooth and fast animation, at a time when PC graphics lacked any kind of acceleration.
