In an interview with Siliconera, David Verfaillie, the Design Director at Double Helix Games revealed Motomu Toriyama’s original script for FRONT MISSION EVOLVED “was quite long” and that they provided feedback to Square. You can read the full quote below.
Siliconera: Vice-versa. Did Double Helix assist with the story?
Design Director: Yes, we also provided quite a bit of feedback to Square on the story. The original script for Front Mission Evolved was quite long, so we provided feedback on which sections we felt were less suited to an action shooter and how to stitch the story back together after removing those parts. We also provided some feedback on character arcs and motivations and how to keep the characters appealing to a Western audience.
