Jason Brownlee is not an unknown in the mobile gaming space. He created the Mobile Game Engines site, a valuable list of currently available frameworks and engines for mobile platforms.
Jason has been reaching out to various mobile game engine developers, including guys from Moai, Corona, Kobol2D, Copperlicht and so on and so forth. The end result is a ~260 pages book, with extensive interviews where you get to know the history and thinking process of the folks behind those frameworks and engines. I was especially surprised seeing that three of the folks in the book are actually Austrians (me, Nikolaus of Irrlicht and Copperlicht fame, and Daniel of Sparrow and Starling fame).
The books a fun read and i recommend getting it. The copy editing isn’t super optimal, but it doesn’t distract to heavily from enjoying the content.
As a special bonus, you can get my entire interview free of charge in PDF form. You’ll get to know some of the history of libgdx and my thoughts on things. And tons of typos, sorry for that.
