   Engines/Frameworks/APIs for 3D Platformer
  Hi everyone,I've already done quite a bit of research and trial and errors and have currently settled on a collection of frameworks and API's instead of a full blown game engine due to not being happy with any particular game engines including Torque, Unity, and UDK.Bullet for Physics and CollisionOpen GL for GraphicsOpen AL for 3D soundand GLFW for joystick and controller inputThe game is essentially a physics based 3D platformer, I just wanted some feedback or advice on the currently selected API's (I'll research and consider any replacements) and maybe even recommendations to full blown game engines to look at if someone swears by one for this particular genre. Any help would be greatly appreciated.Regards,Joe SopkoP.S. Current team of four has knowledge of C++ and Open GL which is a strong reasoning and deciding factor to the toolset.   
  Was exhausted last night and forgot to mention we'd like cross platform capability as well.
