Net Games

Net Games Michael Wolff, Kelly Maloni (Random House, $19) Getting your MUSHes, MUDs, and MOOs mixed up? Here's a passageway to an infinite number of multiuser dimensions where you can be a medieval knight or a space station commander. This guide to games people play in the ever-expanding cyberspace shows you exactly where to go. Want to be an empire builder? Conduct a global war? Rescue a damsel in distress? Play charades? Whether you're into playing footsie or tinysex (using ''descriptive prowess'' to simulate sex), navigating Star Trek's ''final frontier'' or just settling down for a game of backgammon, Net Games offers more than 1,500 addresses, rates the games, and even explains how to hook up to the game-playing highway. If you still don't have a life, this book will at least keep you busy enough to avoid thinking about it. B+ -Daneet Steffens
