You may be familiar with the classic Mavis Beacon Teaches Typing* series of software from Broderbund.
Well, Sega's sublime Typing of the Dead is like Mavis Beacon Teaches Typing ... if Mavis Beacon was a flesh-eating zombie!!
Any self-respecting software developer should be a decent typist. Now you can prove how much of a keyboard ninja you really are, because here's the best part: Typing of The Dead supports 2-player competitive network play over TCP/IP, with comprehensive post-game stat tracking (see screenshot).
It's hard to explain just how wondrously bizarre Typing of the Dead is. It's a challenging, remarkably well thought out typing tutor, a tongue-in-cheek b-grade zombie movie, and the most hilarious multiplayer game experience you'll probably ever have-- all at the same time.
As a zombie enthusiast, I bought Typing of the Dead immediately after it was released in 2001, but I can't find any vendors currently selling the PC version of the game on Froogle or eBay.
