* AlternateCharacterInterpretation: There's a very good argument that Roger is not as dumb as he looks on the aforementioned trope page.
* EarWorm:
** The theme tune, which crops up in at least a dozen variants throughout the series.
** The Skate-O-Rama theme ''will'' drive you mad haunting your brain. It's the perfect combination of catchy, repetitive, and really annoying.
* FunnyMoments: ''Any'' of Roger's deaths.
* NightmareFuel:
** Make Roger fall into Acid or Lava and [[http://tmd.alienharmony.com/rw/sq1vga/pictures/sipacid4.gif get ready to change your pants.]]
** The creepy appearance of the poor dudes in [=SQ4=] with all that headgear could scare some people too.
** The BodyHorror caused by the Pukoid virus is V is as terrifying as it is Squicky. [[spoiler: Pukoid Quirk in particular has a face that ''will'' give you horrible nightmares.]]
** More BodyHorror with Beatrice. Look at her in the cryochamber and leave. Repeat over and over. {{Squick}}!
* ThatOneLevel: In ''Space Quest IV'', the Skate-O-Rama scene where you have to escape the sequel police.
** In ''Space Quest V'', rescuing Cliffy with the EVA pod. Not only you need to locate him first, you must do it quickly before you run out of fuel and oxygen. And don't forget, you also need to return back to the Eureka!
* TechnologyMarchesOn: Signs all over the place, a lot of them very blatant.
** In the VGA remake of SQ1, the Arcada's archive room is explained to have a CRT monitor. And the data cartridge Roger picks up resembles an 8-track tape.
** The ultra-hi-tech supercomputer in SQ4 (or 12) turns out to have a Macintosh 7.5-ish desktop placed over a Windows 3.1 window.
** There's also the long list of old computer stuff in the Genetix lab of SQ5, including SCSI drives, Base-T network, and a 9000 BD modem.
** And a few more examples in SQ6
*** Roger has to read a CD-based magazine. Those didn't last very long back then.
*** In cyberspace he wanders onto a Windows 3.1 desktop.
*** And the narrator plays this for laughs when describing Roger's bed having an 8-track player, complete with an intentional sound glitch.
* CrowningMomentOfAwesome:
--> '''Roger:''' "Djurkwhad is a scaredy-cat! (singsong) Djurkwhad is a scaredy-cat!"
