Don't get me wrong, I'm one of the biggest fans of Final Fantasy, but I'm can kinda understand where they're coming from - as a business.
As a game, no, they're great - Final Fantasy is definitely not broken...
As an investement, on the other hand... they're getting more and more expensive and taking longer and longer to produce - there's no way they are going to be making anywhere near the return on investement that they made on final fantasy 7 thru 12 - and the more complex they get, the LESS money they will make on em.
It's not the greatest business plan, that's for sure...
