Oh, so you settled for the mobile port? That's good.
I never got any of the DS releases. Save for IX, but it got stolen. I'd say, it was a good thing those mobile ports came since now I had the chance to try the DQ series. I already got I-III, plan to get IV-VI eventually; and at least VII and VIII got their 3DS remakes (and already got VIII's). Now I wonder for IX. I don't really want to emulate... oh well, perhaps something will come up.
