Square Enix Thought About Doing Something With Peggle

"We had confirmed that some sort of puzzle system would be utilized as the base, but it took a while to decide which one exactly to go with. The intention for this game had always been to have a single-player focus, so instead of going for a versus-styled interface, we wanted something that would make the enemy-ally positioning very clear," the Gyromancer team said to Siliconera in an interview.

"With this mindset, PopCap games like Zuma and Peggle were actually brought up as candidates."
