Heroes doesn't scratch the itch of an actual "grand adventure" from town-to-town of a mainline DQ game though.
It'd be great if Heroes could be its own full-fledged numbered-DQ tier RPG with action combat.
Horii doesn't think so
(About action combat like Dragon Quest Heroes) "No, Dragon Quest 11 will return to the roots of Dragon Quest. Another action RPG would be like Heroes, and we want to distinguish between the two."
And i'm happy to hear that. There are more than enough RPG's with action-style combat this generation. Something that has more traditional JRPG mechanics with a healthy budget will be a breath of fresh air.
