DQ8 3ds will never come to the west. DQ7 still has not nor has Joker. Good thing is 3DS is BC and grab DQIX on DS and 4,5 and 6. Funny how stupid Square is. DQIX sold 1 million in the US and overall best selling DQ in history..Brave sold 1 million..yet they say they won't bring it over in afraid it won't sell. Personally I think older DQs on SNES are much better than DQ8. DQ8 in a sense if FF7 in peoples first real exposure but best? Hmm debatable. Great game but not sure about best. Personally enjoyed DQIX more but not saying it's better. Speaking of DQ I am hyped about Dragon Quest Heroes west. Yeah we are getting that but no main games Square has made clear. Maybe E3 they shock us all.
DQ8 already has an english localization. DQ7 was remade and would've needed a new one. That's a huge difference and it's the main one that tends to be the deciding factor, especially with such a text-heavy game.
To release this in the west, all they have to do is go back to their english script and just copy it into the new game and then probably get at least half a million sales out of it. They'd be absolutely insane not to do it! Whereas with DQ7, it's a huge game with lots of translation to do. It's also a lesser known game in the west. That's a much bigger gamble for them. DQ8 is no gamble at all, it's guaranteed profit.
