During his keynote talk at the Edinburgh Interactive Festival, Ubisoft CEO Yves Guillemot revealed the scale of the company's success on the DS.
"Ten percent of revenues came from DS casual games last year. We sold 3.5 million Petz games alone," he said.
And such casual games will be a major focus for the company going forward. It's created a new division to make casual and family-friendly games, especially those that can be played together.
