Dragon Quest IV and Dragon Quest V for the Nintendo DS on their own but they had Nintendo publish Dragon Quest VI and Dragon Quest IX. Apparently Square Enix underestimated demand on Dragon Quest V because it sells for about $55-60.
The same thing happened with Super Mario All-Stars, Persona 2, Digital Devil Saga, Shin Megami Nocturne, and Mario Dance Dance Revolution. All of them were eventually reprinted. The price of the game on the resale market is the best indication to a publisher that they didn't make enough and are passing up on some easy money by turning the printing presses back on.
I have a new found love for the Dragon Quest series after playing IX (my first Dragon Quest game) and DQVI. I plan to get Dragon Quest V too, but I think I will be waiting for the inevitable reprint.
Can you think of any CD based games where the publisher didn't reprint the title when the resale price was higher than the retail price? If you do you might be able to convince me to pay the extra money to get my Dragon Quest fix.
