It all started with fond childhood memories.
"The anime that Tatsunoko makes is well known in Japan," said Capcom producer Ryota Niitsuma. "Even now, looking back on them they had a lot of good stories and were really fun. I think a lot of adults in Japan have fond memories of those."
So when the anime studio approached Capcom about making a game based on characters pulled from their five decades worth of work, Capcom jumped at the idea.
The result was 2.5D fighter Tatsunoko Vs. Capcom: Ultimate All-Stars.
