Freesci is a portable interpreter for sci games, such as the space quest series (starting with sq3) or leisure suit larry (2 and sequels).

freesci is still incomplete. you should be able to finish some sci games with it, though. this release has the following limitations (plus some bugs):
- only sci0 games are supported (later versions are being worked on separately
in the experimental "glutton" branch)
- the sci debug functions aren't fully supported (and probably never will be,
since we're using our own debug functions)
it has the following improvements over sierra sci:
- support for various filters and extended drawing operations for graphics
- saving and restoring the game state is possible from more places than the
sierra sci engine allowed (using the debugger functions)
- better debugger
- more portable
- it's free software :-)
