App Game Kit is a powerful game development engine, ideal for Hobbyist and Indie developers. Choose to code in the easy to learn AGK BASIC or use our libraries in C++ & XCode. Write your code once and deploy easily to multiple mobile & desktop platforms. If you're a fan of our Dark Basic range of products then you will love the AGK. With it's easy to code syntax, combined with a fast and reliable gaming engine, creating game apps across multiple devices is now a cinch. You can also code in C++ and call our library of commands. So AGK will suit both hobbyist and professional developer. AGK supports Windows, Mac, Linux, iOS, Android, Raspberry Pi and HTML5.

What I like about AGK2 is that it is great for quick and easy prototyping but also for creating complete games without loosing focus on finishing a game which in my opinion does happen often when using big triple A engines. Besides that, AGK has a very active and helpfull forum.

Some cool stuff from AGK2 I enjoy:

supporting the main mobile platforms: iOS and android
Recently added: HTML5 support
two levels of coding you can choose from (basic or c++ for building native)
both 2d and 3d support
very easy implementation of iap and adds (ios and android)
ios gamecenter and google play games
also runs on the rapsberry Pi, how cool is that!

In short: AGK2 is cool!
