What type of typing games are there?

I heard about Typing of the Dead and was wondering if any other typing games like such are out there.|||Mavis Beacon Teaches Typing has proper typing tests and games too, although they're more like mini-games, such as spelling out words which an iguana eats and making icicles for penguins to stand on out of words, they're time based and a lot of fun when you have time to spare, they do increase your typing efficiency too.
