My point being, FF15 is the new Duke Nukem Forever. At over 7 years, this game is well on its way to reaching the 11/13 year record set by the Duke.

September , 2011

The problem is that Versus was announced too early .. way before the actuall development starts, the game is not over-developed as most people think.

I swear: They promised to keep the public updated on KH3 and FFXV with regular trailers interviews etc.

Man...what a joke Square has become aside from the occasional Dragon Quest and great HD remake like KH 1,5 remix

Just when i was slowly warming up because of FFXIV...

They can shove that action packed so-called FF right where it belongs. Funny thing would be abysmal sales for FFXV causing them to end the franchise because of lack of interest. Lesson 1 in how to ruin a good product.
