QTads is a cross-platform multimedia interpreter for Tads (Text Adventure Development System) games. Both Tads versions in use today (Tads 2 and Tads 3) are supported. It should be easy to port to a range of platforms, including embedded devices. MIDI, Ogg Vorbis, MP3, and WAV sound formats are supported.
advent4 is a port of the original Colossal Cave text adventure to Unix. It should work without any change on HP-UX, Sun Solaris, *BSD, and GNU/Linux systems. The actual license of this program is unknown, although most people agree that it is likely to be considered to be under the public domain.
