1B of that being in Clash of Clans
Interesting to see them exit -- Clash of Clans hadn't showed signs of slowing down, especially given that they recently released on Android.
Big contrast to Gungho (the purchaser) and Rovio, which is worth $455,438,581 and $145,714,888.
Rovio hasn't been a major player in terms of being a top grossing app recently -- they get good downloads and have brand presence, but in the age of IAP based free to play revenue (24 top grossing apps out of top 25 are free: https://sensortower.com/ios/rankings/top/iphone/us/all-categ...) Rovio's app based model isn't as sticky as long term freemium titles with long term progression. Not to say that Rovio isn't doing great in other parts of it's business!
Think the valuation on Gungho is significantly off though. Gungho made 763 million the first half of 2013, compared to 455 million (http://www.pocketgamer.biz/r/PG.Biz/GungHo+Online+news/news....)
