charlequin said:DQ showed up because the DS was already selling well --
I agree with this. DQ came to the DS because it already had the userbse, and that is largely thanks to Nintendo's first party offerings. Yes FFIII, GS, and other 3rd party games helped, but the real reason for this large userbase is due to Brain Training, Nintendogs, Animal Crossing, etc...
Its nice to think that 3rd parties and Nintendo brought the DS to it's userbase together, but I believe that Nintendo wouldn't be getting this kind of support had they not brought the userbase up to a certain level relatively on their own (since 3rd parties weren't giving it the level of support they are now). Kind of like a vicious cycle of 3rd parties not giving it major support until it has the userbase, but it can't get the userbase without the major support. First party games brought the userbase up to that level where 3rd parties would take it seriously imo.
