Translation of paragraph 1: Ueda Fumito: In the first stages of development, "Wander to Kyozō" was called "NICO," short for "Next Ico." The idea for our new game was to use what we had learned in "Ico" and come up with something new. However, "NICO" was nothing more than a temporary project name and it was clear from the beginning that the title would change.
