Different budgets lead to different expectations. Dragon's Dogma 2 wasn't really a a huge success either. And that probably played a part in the director/producer leaving Capcom.
Square Enix is simply out of touch with reality.
Final Fantasy is not a 10m seller IP like they would like it to be.
And it's their fault it isn't one with all the mediocrity they released for a decade that damaged the brand.
They're now finding out they're left with their 2.5-5m longtime fanbase and the rest of the market, especially younger generations, don't care about the IP.
They took ten years to deliver the game with no compromises, not half assed that the fanbase wanted with FF7 Rebirth.
They're also creating an identity problem with the constant deep, almost genre swapping changes to the formula they make to try to follow trends (FF16 was born with the mission to ride the success of Game of Thrones...) in the end they constantly lose groups of fans while hardly gaining others and the net effect is no growth.
Their solution to these issues with multiplatform is just a band-aid.
They need to step up the quality of their products but quite frankly I fear the opposite might happen, lower sales will lead to big budgets not being justified and even more cut corners.
