As part of the promotion for their new radio series of
The Hitchhikers Guide to the Galaxy the clever people at the BBC have updated the classic text-based
Hitchhikers Game by Douglas Adams (circa 1984) to be playable over the web. It also has images (by the original artist), which add a certain something to the gameplay.
This particular one was a little before my time when it first came out, although the text-based adventure takes me straight back to playing the infamous
Leather Goddess of Phobos which I played for months and probably didn't get anywhere.
Also the new episodes are available to listen to
here, although opening the window to listen to them crashed my firefox quite nicely.
