Project Anarchy was released a few months ago for FREE to develop and deploy for mobile platforms. They are supposed to be releasing a Pro License within a month that will let you deploy to Consoles and Desktop. Project Anarchy uses Havok's tools and you can code in C++ or Lua. If you don't know who Havok is I suggest you look into them. The Havok tool set is nothing short of amazing and has been used for a very long time to create AAA titles, except they were only available for larger companies. Now that they are starting to release them to everyone, things will surely become interesting.
Once the community grows and there are all kinds of tutorials and a big community to help on the forum, pretty sure this will be your best choice by far. They are also working on 2D game development components, which just might make this the best 2D Lua engine as well, since it allows you to deploy to pretty much every platform and device out there. Now the question is how much the Pro License will be. I will update when it comes out.
