I was wondering what is the suggested framework/engine for creating games for Windows Store/WP8 that is also able to port to other devices as well. I want to try to find something that uses C++ which I have looked at Cocos2D-X and have been unsuccessful in getting their beta to work and haven't got any feedback yet on their forums. Is there something just as equally as good for C++? C# is also another option which right now I'm waiting for Synapse Gaming to release their next version of their SunBurn engine as it will be platform independent. Anyways, I'd like to hear what suggestions you all might have and will appreciate any feedback.
