If we lived in Japan and needed to learn English, English of the Dead would clearly be our choice of software. Yet, we're not saying that Paon doesn't have a fun idea for their English training game, too. New Horizon English Training Course DS might not have zombies, but it does have Judo.
As you may have guessed, the way in which this title handles its English quizzes is through sports minigames. It's unclear how exactly the Judo game works, but there's also a marathon event (during which players must write out the correct letters quickly in order to run fast), and a weight training game (which has players identify whether or not a translation is correct).
Of course, in our hearts, zombies still win -- every time.
