Strange Adventures in Infinite Space was a sci-fi roguelike developed by Digital Eel and published by Cheapass Games back in 2002.
It’s about captaining an Enterprise-esque starship as you boldly go where nobody is legally allowed to go, exploring an alien system before it’s declared open. You bounce from planet to planet finding alien species to trade or do battle with, discovering new technology, and trying to make it home before the time limit’s up.
This new updated version is compatible with modern operating systems and remains DRM-free as well as pay-what-you-want. It also comes with a pack of community-made mods like The Urluquai Crusade and Even Stranger Adventures in Infinite Space.
Digital Eel made a couple of sequels that are available on Steam, Weird Worlds: Return to Infinite Space and Infinite Space 3: Sea of Stars, but the original game stopped being supported and was victim to various graphical glitches from Windows 7 onwards.
