This article attempts to documents the differences between the AGI and SCI versions of Space Quest I.

The InterfaceEdit

AGI (Tandy/EGA) is a text based interface. However, the other EGA/VGA versions uses SCI1, which is a point-and-click interface.

Locations Edit

Ulence Flats Edit

  • Due to the new interface, it is now possible to talk to the characters in the bars.
  • Touching the force field multiple times is now lethal.


Slot MachineEdit

In the AGI version, the player must play the slot machine as a game of luck (except in later versions where typing "HOLY SHIT" at the slot machine screen will enable a cheat). In the SCI version, a magnet can be found on the Arcada, which can then be attached to the slot machine for a guaranteed win.

In both versions, getting three skulls results in the player being vaporized. In the AGI version, the raygun emerges from the machine; in the SCI version, it is externally mounted.

Graphical DifferencesEdit

Practically everything is in a graphically different style. Here are some of the major differences:

Roger WilcoEdit

In AGI , Roger has brown hair, and a white and gray uniform. However, in the SCI remake, they decided to model Roger after the latest version at that time - Space Quest IV - and therefore has blonde hair and a white and purple uniform.

The ArcadaEdit


The DeltaurEdit

In the AGI version, the Deltaur appears as a generic sci-fi star cruiser, whereas in the SCI version it looks like a giant insect.

Easter EggsEdit


In AGI , if Roger pushed the DO NOT PUSH button he ends up in The Daventry Zone, however in SCI he ends up at Nottingham Castle.

Please feel free to contribute your own thoughts or work to complete it, but keep in mind that what is here is even more tentative than MOST of the Omnipedia, which is already pretty darn tentative.
