This warning says it all: "The game will kill you frequently. It's a bit mean like that."
Thirty years ago, Hitchhiker's Guide to the Galaxy author Douglas Adams and Infocom's Steve Meretzky designed an interactive fiction version of the classic work of scifi humor. The game was a huge hit; according to the BBC, it sold 350,000 copies, making it a big seller for 1984.
The BBC updated the game with graphics in 2004, and now has polished up the game once more for a 30th anniversary edition. It retains the wit and gameplay of the original, along with all the devious puzzles and the wicked ways to die. Clear your schedule and prepare for a bit of frustration.
