Based on the feedback I've gotten so far (thanks to everyone) here is my current roadmap for HGE:[*]Continue enhancing documentation and examples.[*]Add more language bindings.[*]Add a physics system.[*]Add a developer IDE that integrates and expands the feature set.[*]Add cross-platform support.

It's subject to change based on feedback so feel free to comment.

I've also updated the HGE page.
