Submission + - Multiplayer Zork (icculus.org) 1
netfunk writes: I took Zork 1 and made it into a multiplayer game! You can try it yourself by telnetting to multizork.icculus.org with some friends. Telnet seemed appropriate for a game from 1980, at least until I can figure out how to efficiently send everyone a 300 baud modem. A detailed technical explanation about hacking the Z-Machine to make this work is over here and source code is, of course, available. Enjoy, and don't get eaten by a grue!
