"As a matter of fact, at the beginning [Crisis Core: Final Fantasy VII] was expected to be full action," Tabata tweeted. "Many of the staff were skilled at RPGs, so the design changed to a RPG battle where Zack can move around inside." Tabata gives the resulting system his approval.
Tabata also revealed a part of Crisis Core: Final Fantasy VII was cut because it was too big to fit on the UMD. A piece between the Shinra Mansion and escape to Midgar didn’t make it into the final game. Crisis Core: Final Fantasy VII explored the drama of the relationship between Zack and Cloud, but since this was cut the game focused on Zack’s life as a soldier instead.
"By the way, for more than 10 years I wanted to make a gun action genre game," Tabata poured to his Twitter followers. "For a first try, the PSP is a good scale." As you’re probably aware of, The 3rd Birthday has third person mechanics even though Square Enix calls a "cinematic action RPG" in Japan.
