Strange Adventures in Infinite Space

Strange Adventures In Infinite Space (SAIS) is a hybrid strategy/adventure computer game. It was created by the independent game development group Digital Eel. In the game players explore a "plausibly implausible" (fictional) region of the Milky Way galaxy called The Purple Void.

Unlike "one time through" story games, SAIS sets up differently each time it is played. Stars, black holes, planets, nebulae, artifacts, alien patrols, gadgets, lifeforms and dozens of events and encounters are randomized for each game session. It is also very short. Game sessions typically last from 3 to 20 minutes, hence the game's tagline "Explore the galaxy in 20 minutes or less!"

Ernest Adams, writing for Gamasutra in 2005, described SAIS as "The perfect short game."

SAIS was released for PC and Mac on March 15, 2002 by the award-winning boardgame developer/publisher, Cheapass Games, and later for Pocket PC and Palm by British developer/publisher, Astraware.

As of November 11, 2005, the source code is freely available under the GNU GPL, though other game content besides the code is still proprietary. Since September 28, 2009, SAIS itself is available as freeware.

SAIS's sequel, Weird Worlds: Return to Infinite Space features far more content and options, and is currently available for Windows and Mac.

Fred Ford and Paul Reiche III are listed in the "inspiration" section of the game credits, probably meaning that the game is partially inspired by Star Control series.
