Digital: A Love Story
I really wonder how I missed this one. While I'm sure most of you have already been playing this, I only discovered it a few days ago and have been hooked ever since. It's called Digital: A Love Story, and it's an interactive story set in 1988, written/created by Christine Love. The interface of the game is the Amiga Workbench, and you progress through the story by reading, replying, and hacking BBSs using your modem.
