I have to say, this is pretty damn cool. The BBC Radio 4 web site
has a Flash remake of Infocom's Hitchhiker's Guide to the Galaxy
text adventure adaptation, considered by many of to be the best title in Infocom's catalog.
The main game play is still done through a text parser (yay!) but they've added a little graphic interface as well. You can move to different locations by clicking and you've got a separate inventory screen.
Pretty nifty, plus you can create an account on the site to save your game (pretty much required after I remembered how bloody hard the game is, even if it does closely follow Douglas Adams' book.)
