Get your affairs in order. An engine for text adventure games called Quest has been released as open source. The Zork adventure game on PDP-11 pretty much destroyed my social life in 1980 — though come to think of it, it was not healthy in the first place and may have never revived. And you would be correct if you observed that not everyone had a PDP-11 sitting around in the living room. We played it at work, after our project managers went home for the day. In fact, my project manager actually showed it to me; it was probably an evil plot to condition us to sleep under our desks. Now you can create your own spelunking adventures — or whatever kind you want.
