Mobile game franchises like Angry Birds, Puzzle & Dragons and Clash of Clans aren't just a threat to the traditional games industry individually: their creators willingness to team up is also challenging the mindsets of bigger publishers.
Witness a new partnership between Angry Birds developer Rovio Entertainment and Puzzle & Dragons developer GungHo Online, which was announced today, hot on the heels of a recent collaboration between GungHo and Clash of Clans creator Supercell.
Between 18 November and 1 December, Puzzle & Dragons will host an Angry Birds-themed dungeon, featuring some of the most popular characters from Rovio's feathery franchise.
"Angry Birds is one of the most recognisable entertainment franchises in the world, and we are thrilled to be working alongside Rovio to give our fans a look at what it would be like if Angry Birds characters invaded the world of Puzzle & Dragons," said the latter game's creator Daisuke Yamamoto in a statement.
For its part, Rovio will be holding a contest for Angry Birds fans to send in their illustrations of how the two games might come together.
It's a meeting of monster mobile franchises. Angry Birds ended 2012 with 263m monthly active players according to its last annual financial results, with the games and related products earning the company €152.2m (£129m) in revenues for that year.
That pales in comparison to Puzzle & Dragons, though, which with just 20m downloads in Japan helped GungHo make $446m of revenues in the second quarter of 2013, and was estimated to be the fourth top grossing iOS app and the top grossing Android app on the Google Play store globally in September.
GungHo has run two promotions within Puzzle & Dragons for Supercell's Clash of Clans, the most recent being a week-long event in October following Puzzle & Dragons' release in the UK with another themed dungeon.
GungHo also invested $300m in Supercell as part of the latter company's recent $1.5bn strategic investment round, alongside Japanese telco SoftBank.
