L'ha detto Tai Yasue, co-director del gioco, in un'intervista a Londra.

QuoteWhen I asked whether I could safely infer that that Star Wars and Marvel are not off-limits, Yasue confirmed that they are being considered. "Well, yeah. They're all under consideration," he said. "Nothing's off-limits, we're considering all of the worlds. There are so many wonderful concepts. We're happy about that, but at the same time it's really tough to choose."
