The problem with Square is that they want to go all out with their budgets. They need to embrace middle tier development.
I believe Nomura's influence has bloated the series budgets.
They can do a modest remake for a profit, but they want to do their crazy polished treatment, which you saw in FFXIII, but didn't translate to a good game. Kitase has also spoken about the FF polish.
What the fuck?
How could you possibly blame Nomura for this shit? His franchise is the one that has been on Handhelds for the past 2 installments. He also pushed for other handheld projects and did art for things like TWEWY.
Money problems can be found by failures like XIV, White Engine, and taking Nomura's team from him when he needs to build a game.
