Here's another reminder that mobile games are big business - In IGG's annual report published earlier this year they revealed that Lords Mobile is now making about $50 million per month in revenue worldwide (and still growing). That's a staggering sum of money for a single mobile game. Especially one that's so similar in core gameplay to dozens of other mobile strategy games like Game of War and Clash of Clans.

Just to put that $50 million a month figure into context - Runescape brings in "only" $98 million per year while Square Enix makes ~$280 million per year from ALL of their MMOs combined (Final Fantasy XIV, Final Fantasy XI, and Dragon Quest X). Lords Mobile makes 6x as much money as Runescape yearly and over 2x as much money as every Square Enix MMO combined. Wow!
