I know nothing about DQ, but would people argue that FF1 was more important and influential than FF4? Because I'd say 4 had more impact and its influence is felt on the series more now, and it might be a bigger deal to the genre.
Like I don't think you can just look at sales numbers because that ignores the impact a game might have on developers.
