Newsbrief: We already knew that GungHo Online's mobile hit Puzzle & Dragons is proving rather popular, generating around $2.5 million daily back in February. As of today, GungHo is now valued at just over 1.54 trillion yen ($15.1 billion), as industry consultant Serkan Toto reports, meaning that the company now has a greater market cap than Nintendo's 1.53 trillion yen ($15.0 billion). The game now has over 13 million registered users in Japan -- around 10 percent of the country's population -- and generated $113 million in sales in April, which translates to around $3.77 million a day.
