Kali? IHHD? Case's Ladder? This timeline sucks (Score 1)

What the hell is up with this timeline? The author goes into a lot of detail on what are apparently his favorite MUDs, but he totally skips over some of the most important advances that have enabled internet gaming and, thus, virtual worlds. What about IHHD (Internet Head to Head Daemon) which allowed people to play games like Descent against each other on the internet before even PPP accounts were widespread? What about Case's Ladder, one of the first widespread ladders for competitive gaming? What about kali, which was one of the first means for emulating IPX games over the internet. What about gaming leagues, such as the International Warcraft League (IWL)? I think the author of this timeline may have honestly wanted to create a good timeline, but to call it a "timeline of virtual worlds" is a little premature without doing all the research required. Just my $0.02.
