Pocket Gamer: I'm old enough to (at least vaguely) remember two very distinct typing-related products. One of them was for DOS way back in the day. I forget the name, but essentially it was a very dry edu-tainment title that aimed to teach you how to touch-type.
The other was The Typing of the Dead, the House of the Dead spin-off that attempted to jam zombie-shooting together with keyboard mastery.
Learn with Pokemon: Typing Adventure is more similar to the latter title, in that it doesn't necessarily develop new QWERTY-related skills as much as hone those you already have.
