>>33234053How stupid you're thinking GF is omnipotent and not rely on Nintendo resources? They have absolutely control over GF and if they release something which could harm the brand they'll crush them. There's no getting away with releasing same game twice.
The simple answer to why they're not marketing it as much as SM is that it's not required. SM was completely new entry in the series which completely new art style, major overhaul in terms of graphic presentation and setting. Such huge change could turn some people off Pokemon franchise which required them to market the shit out of 7th gen so people would know everything about this gen even before they're going to buy it.
With USUM they already has their bases established why the fuck people think they should invest same amount of resources and time into marketing it same way is beyond me.
