Epic Mickey was originally in development for Xbox 360 and PS3, Warren Spector has confessed.
Speaking in an interview with ONM, Spector revealed that Disney Interactive Studios allowed him to focus on the Wii version alone in order to make "the very best game" he could.
"The reality is that we started Wii development in 2008, but before that we were a PC, PS3, and 360 title," Spector told Nintendo mag.
"It's burned in my brain - Graham Hopper [Disney Interactive boss] pulled me into my office one day and said 'What does it take to deliver on the goals we have for this product? And I said, well, you need enough time and enough money to be competitive. And it'd be awfully nice if we could focus on one platform."
"At that time we were talking about a Wii port and I was begging people - no, we can't just port to the Wii, it's not going to work. It needs to be its own game. A lot of the design ideas just won't work on the Wii, we need to give the Wii its dues. Graham looked at me and said 'What do you think about a Wii exclusive?' And I went 'Holy cow - yeah!'
"They walked away from three other platforms - no other publisher on the planet would have done that. It was a magic moment for me. No-one has even mentioned other formats since that point."
