  # cat /dev/random | grep "the answer to life, the universe and everything" | sed -e 's/the answer to life, the universe and everything/42/'

I still play adventure, on my school's quad-cpu Sun Enterprise server, and on my two Commodore Pets at home, where I first learned the game. I think Hunt the wumpus and Solitaire are the only games on that list that I've played, and didn't really care much for either, after mucking around in Colossal Cave.
