FF music are much more recognizeable and popular (you can see album sales). Also, let's wait to see whether the franchise has died or not, since there might still be a Theatrhythm KH in the pipeline.
Low preorders don't signal anything substantial (plenty of games have low preorders and then sell incredibly well); lack of multiplayer is a non-issue if the primary target is DQ fanbase; being the first MC clone should help and not harm...?
Considering how much effort was put into the DLC...
What i was trying to say by that was that you can do your kind of analysis to justify any agenda that one might have. I mean even FF Theatrhythm could be said to be a failure when you think of it as a rhythm game spinoff of one of the most popular franchises where fans are mad about the music, as per album sales. The game was on a the most popular platform at the time and catered to the demographics by its art style. Looking at the results which didnt even crack 200k and they had to release a phone version of the game,Square should move the franchise to Sony platforms where FF sells the most and rhythm games such as Miku do great numbers.
Just to clarify I'm not actually suggesting that, just showing how perception can be skewed, something that happens a lot in these threads to argue that all games and publishers should jump ship to my favourite platform.
Regarding DQB, if the game was targetd at DQ crowd then we really ought to have been vary as DQ games tend be front loaded as indicated usually by preorders.
