The 3rd Birthday producer Hajime Tabata has said with more time, Aya Brea's third outing would have been a full console game.
"If we had been given more time on this project from the beginning, we would have switched platforms from the PSP to a home console," Tabata told Siliconera.
"I would have then liked to have created a shooting-based survival RPG game, where the player is placed in an even more desperate situation, facing insurmountable odds and having to continually fight to survive."
The producer said the game's lock-on action was deigned around the PSP's hardware.
"Realizing the hardware and control limitations of the PSP, the game was designed to have firearms as the fundamental attack action within a lock-on action system," he said.
"That’s why the development differs from the development of a traditional TPS game. We also faced many difficulties outside of development."
The 3rd Birthday releases on March 29 in the US and April 1 in Europe.
