IwGame Engine – Free Open Source Mark-up Driven Game Engine for iOS, Android, Bada, Blackberry
IwGame Engine – Free open source mark-up driven rapid game development engine for smart phones, tablets, desktop and emerging technologies
The IwGame engine is a mark-up driven game engine that uses an XML based language called XOML (similar in design to Microsoft's XAML and Adobes MXML), allowing rapid production of complex game layouts, front-ends, very complex multi-part key frame animations, actors, scenes, events actions, resources etc..
The latest version along with historical versions of the IwGame Engine are available for free download at the drmop.com blog at http://www.drmop.com/
Pocketeers Limited's first game title created using the IwGame engine called cOnnecticOns has just gone live on the Android Market and will soon also be available for iPhone, iPad, iPod, Samsung Bada and Blackberry Playbook. This game was created simultaneously for iOS, Android, Bada and Playbook in just 3 days. The game code is over 90% mark-up based!
The full source to cOnnecticOns will be released this weekend on http://www.drmop.com
For more information about cOnnecticOns please visit http://appliter.com/
The game can be downloaded directly from the Android Market at https://market.android.com/

Future releases will include support for in-app purchasing, analytics, video playback, camera access and 3D gaming.
he IwGame engine also features the IwGameAds SDK, which is a unified cross platform ad collection, display and processing SDK using eye catching animation to increase CTR (currently 3% - 8%, varying by platform). Direct and indirect support for Inner-active, AdFonic, Vserv, InMobi, BuzzCity, JumpTap, ZestAdz / Komli Mobile, Mojiva, Millennial Media, AdMob, Amobee and AdModa a networks.
