Capcom’s Shu Takumi, who is a lead developer on the Ace Attorney Series, was interviewed by OtonaFami and explains how the collaboration on Professor Layton vs. Ace Attorney got started. Here is a small piece of the interview:
OF: Could you tell us how this collaboration came to be?
Takumi: Hino, director of Level 5, came to Capcom and the project started early 2010. I was busy with Ghost Trick at the time, and I was to join the team after finishing that…. but at that time, nobody had any idea what kind of game it would be (laugh).
